The Latine/Hispanic population in the United States comprises one of the largest and youngest skin of color communities.^1,2 In 2020, this group accounted for 19% of all Americans—a percentage expected to increase to more than 25% by 2060.³

It must be emphasized that the Latine/Hispanic community in the United States is incredibly diverse.⁴ Approximately one-third of individuals in this group are foreign-born, and this community is made up of people from all racialized groups, religions, languages, and cultural identities.² The heterogeneity of the Latine/Hispanic population translates into a wide representation of skin tones, reflecting a rich range of ancestries, ethnicities, and cultures. The percentage of individuals from each origin group may differ according to where they live in the United States; for instance, individuals who identify as Mexican comprise more than 80% of the Latine/Hispanic population in both Texas and California but only 17% in Florida, where more than half of Latine/Hispanic people identify as Cuban or Puerto Rican.^4,5 As a result, when it comes to skin cancer epidemiology, variations in incidence and mortality may exist within each of these subgroups who identify as part of the Latine/Hispanic community, as reported for other cancers.^6,7 Further research is needed to investigate these potential differences.Unfortunately, considerable health disparities persist among this rapidly growing population, including increased morbidity and mortality from melanoma and keratinocyte carcinomas (KCs) despite overall low lifetime incidence.^8,9 In this review, the epidemiology, clinical manifestation, and ethnic disparities for skin cancer among the US Latine/Hispanic population are summarized; other factors impacting overall health and health care, including sociocultural factors, also are briefly discussed.

Terminology

Before a meaningful dialogue can be had about skin cancer in the Latine/Hispanic population, it is important to contextualize the terms used to identify this patient population, including Latino/Latine and Hispanic. In the early 1970s, the United States adopted the term Hispanic as a way of conglomerating Spanish-speaking individuals from Spain, the Caribbean, and Central and South America. The goal was to implement a common identifier that enabled the US government to study the economic and social development of these groups.¹⁰ Nevertheless, considerable differences (eg, variations in skin pigmentation, sun sensitivity) exist among Hispanic communities, with some having stronger European, African, or Amerindian influences due to colonization of their ­distinct countries.¹¹

In contrast, Latino is a geographic term and refers to people with roots in Latin America and the Caribbean (Table 1).^12,13 For example, a person from Brazil may be considered Latino but not Hispanic as Brazilians speak Portuguese; alternatively, Spaniards (who are considered Hispanic) are not Latino because Spain is not a Latin American country. A person from Mexico would be considered both Latino and Hispanic.¹³

Melanoma

Melanoma, the deadliest form of skin cancer, is more likely to metastasize compared to other forms of skin cancer, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). For Latine/Hispanic individuals living in the United States, the lifetime risk for melanoma is 1 in 200 compared to 1 in 33 for NHW individuals.¹⁴ While the lifetime risk for melanoma is low for the Latine/Hispanic population, Hispanic individuals are diagnosed with melanoma at an earlier age (mean, 56 years), and the rate of new cases is marginally higher for women (4.9 per 100,000) compared to men (4.8 per 100,000).^15,16

Typical sites of melanoma manifestation in Latine/Hispanic individuals include the torso (most common site in Hispanic men), lower extremities (most common site in Hispanic women), and acral sites (palms, soles, and nails).^9,16,17 Anatomic location also can vary according to age for both men and women. For men, the incidence of melanoma on the trunk appears to decrease with age, while the incidence on the head and neck may increase. For women, the incidence of melanoma on the lower extremities and hip increases with age. Cutaneous melanoma may manifest as a lesion with asymmetry, irregular borders, variation in pigmentation, large diameter (>6 mm), and evolution over time. In patients with skin of color, melanoma easily can be missed, as it also typically mimics more benign skin conditions and may develop from an existing black- or dark brown–­pigmented macule.¹⁸ The most common histologic subtype reported among Latine/Hispanic individuals in the United States is superficial spreading melanoma (20%–23%) followed by nodular melanoma and acral lentiginous melanoma.^16,19 Until additional risk factors associated with melanoma susceptibility in Hispanic/Latine people are better elucidated, it may be appropriate to use an alternative acronym, such as CUBED (Table 2), in addition to the standard ABCDE system to help recognize potential melanoma on acral sites.¹⁸

Keratinocyte Carcinomas

Keratinocyte carcinomas, also known as nonmelanoma skin cancers, include BCC and SCC. In comparison to the high-quality data available for melanoma from cancer registries, there are less reliable incidence data for KCs, especially among individuals with skin of color.²⁵ As a result, KC epidemiology in the United States is drawn largely from case series (especially for individuals with skin of color) or claims data from small data sets often from geographically restricted regions within the United States.^25,26

Basal Cell Carcinoma—Basal cell carcinoma is the most common malignant skin cancer in Latine/Hispanic individuals. Among those with lighter skin tones, the lifetime risk for BCC is about 30%.^27,28 Men typically are affected at a higher rate than women, and the median age for diagnosis is 68 years.²⁹ The development of BCC primarily is linked to lifetime accumulated UV radiation exposure. Even though BCC has a low mortality rate, it can lead to substantial morbidity due to factors such as tumor location, size, and rate of invasion, resulting in cosmetic and functional issues. Given its low metastatic potential, treatment of BCC typically is aimed at local control.³⁰ Options for treatment include Mohs micrographic surgery (MMS), curettage and electrodessication, cryosurgery, photodynamic therapy, radiation therapy, and topical therapies. Systemic therapies are reserved for patients with locally advanced or metastatic disease.³⁰

Latine/Hispanic patients characteristically present with BCCs on sun-exposed areas of the skin such as the head and neck region. In most patients, BCC manifests as a translucent pearly nodule with superficial telangiectasias and/or a nonhealing ulcer with a central depression and rolled nontender borders. However, in patients with skin of color, 66% of BCCs manifest with pigmentation; in fact, pigmented BCC (a subtype of BCC) has been shown to have a higher prevalence among Hispanic individuals, with an incidence twice as frequent as in NHW individuals.³¹ In addition, there are reports of increased tendency among Latine/Hispanic individuals to develop multiple BCCs.^32,33

The relationship between UV exposure and KCs could explain the relatively higher incidence in populations with skin of color living in warmer climates, including Hispanic individuals.³⁴ Even so, the development of BCCs appears to correlate directly with the degree of pigmentation in the skin, as it is most common in individuals with lighter skin tones within the Hispanic population.^25,34,35 Other risk factors associated with BCC development include albinism, arsenic ingestion, chronic infections, immunosuppression, history of radiation treatment, and history of scars or ulcers due to physical/thermal trauma.^35-37

Squamous Cell Carcinoma—Squamous cell carcinoma is the second most common skin cancer among Latine/Hispanic patients. In contrast with NHW patients, evidence supporting the role of UV exposure as a primary risk factor for SCC in patients with skin of color remains limited.^25,38 Reports linking UV exposure and KCs in Hispanic and Black individuals predominantly include case series or population-based studies that do not consider levels of UV exposure.²⁵

More recently, genetic ancestry analyses of a large multiethnic cohort found an increased risk for cutaneous SCC among Latine/Hispanic individuals with European ancestry compared to those with Native American or African ancestry; however, these genetic ancestry associations were attenuated (although not eliminated) after considering skin pigmentation (using loci associated with skin pigmentation), history of sun exposure (using actinic keratoses as a covariate for chronic sun exposure), and sun-protected vs sun-exposed anatomic sites, supporting the role of other environmental or sociocultural factors in the development of SCC.³⁹ Similar to BCCs, immunosuppression, chronic scarring, skin irritation, and inflammatory disease also are documented risk factors.^9,32

Among NHW individuals with lighter skin tones, SCC characteristically manifests on sun-exposed areas of the skin such as the head and neck region. Typically, a lesion may appear as a scaly erythematous papule or plaque that may be verrucous in nature or a nonhealing bleeding ulcer. In patients with more deeply pigmented skin, SCC tends to develop in the perianal region and on the penis and lower legs; pigmented lesions also may be present (as commonly reported in BCCs).^9,32,36

Unfortunately, the lower incidence of KCs and lack of surveillance in populations with skin of color result in a low index of clinical suspicion, leading to delayed diagnoses and increased morbidity.⁴⁰ Keratinocyte carcinomas are more costly to treat and require more health care resources for Latine/Hispanic and Black patients compared to their NHW counterparts; for example, KCs are associated with more ambulatory visits, more prescription medications, and greater cost on a per-person, per-year basis in Latine/Hispanic and Black patients compared with NHW patients.⁴¹ Moreover, a recent multicenter retrospective study found Hispanic patients had 17% larger MMS defects following treatment for KCs compared to NHW patients after adjustment for age, sex, and insurance type.⁴²

Hispanic patients tend to present initially with SCCs in areas associated with advanced disease, such as the anogenital region, penis, and the lower extremities. Latine and Black men have the highest incidence of penile SCC, which is rare with high morbidity and mortality.^32,43,44 The higher incidence of penile SCC among Hispanic individuals living in southern states could correspond to circumcision or HPV infection rates,⁴⁴ ultimately impacting incidence.⁴⁵

Dermatofibrosarcoma Protuberans

Dermatofibrosarcoma protuberans (DFSP) is a rare locally aggressive cutaneous sarcoma. According to population studies, overall incidence of DFSP is around 4.1 to 4.2 per million in the United States. Population-based studies on DFSP are limited, but available data suggest that Black patients as well as women have the highest incidence.⁴⁶

Dermatofibrosarcoma protuberans is characterized by its capacity to invade surrounding tissues in a tentaclelike pattern.⁴⁷ This characteristic often leads to inadequate initial resection of the lesion as well as a high recurrence rate despite its low metastatic potential.⁴⁸ In early stages, DFSP typically manifests as an asymptomatic plaque with a slow growth rate. The color of the lesion ranges from reddish brown to flesh colored. The pigmented form of DFSP, known as Bednar tumor, is the most common among Black patients.⁴⁷ As the tumor grows, it tends to become firm and nodular. The most common location for DFSP is on the trunk or the upper and lower extremities.⁴⁷

Although current guidelines designate MMS as the first-line treatment for DFSP, the procedure may be inaccessible for certain populations.⁴⁹ Patients with skin of color are more likely to undergo wide local excision (WLE) than MMS; however, WLE is less effective, with a recurrence rate of 30% compared with 3% in those treated with MMS.⁵⁰ A retrospective cohort study of more than 2000 patients revealed that Hispanic and Black patients were less likely to undergo MMS. In addition, the authors noted that WLE recipients more commonly were deceased at the end of the study.⁵¹

Despite undergoing treatment for a primary DFSP, Hispanic patients also appear to be at increased risk for a second surgery.⁵² Additional studies are needed to elucidate the reasons behind higher recurrence rates in Latine/Hispanic patients compared to NHW individuals.

Factors Influencing Skin Cancer Outcomes

In recent years, racial and ethnic disparities in health care use, medical treatment, and quality of care among minoritized populations (including Latine/Hispanic groups) have been documented in the medical literature.^53,54 These systemic inequities, which are rooted in structural racism,⁵⁵ have contributed to poorer health outcomes, worse health status, and lower-quality care for minoritized patients living in the United States, including those impacted by dermatologic conditions.^8,43,55-57 Becoming familiar with the sociocultural factors influencing skin cancer outcomes in the Latine/Hispanic community (including the lack of or inadequate health insurance, medical mistrust, language, and other cultural elements) and the paucity of research in this domain could help eliminate existing health inequities in this population.

Health Insurance Coverage—Although the uninsured rates in the Latine population have decreased since the passage of the Affordable Care Act (from 30% in 2013 to a low of 19% in 2017),⁵⁸ inadequate health insurance coverage remains one of the largest barriers to health care access and a contributor to health disparities among the Latine community. Nearly 1 in 5 Latine individuals in the United States are uninsured compared to 8% of NHW individuals.⁵⁸ Even though Latine individuals are more likely than non-Latine individuals to be part of the workforce, Latine employees are less likely to receive employer-sponsored coverage (27% vs 53% for NHW individuals).⁵⁹

Not surprisingly, noncitizens are far less likely to be insured; this includes lawfully present immigrants (ie, permanent residents or green card holders, refugees, asylees, and others who are authorized to live in the United States temporarily or permanently) and undocumented immigrants (including individuals who entered the country without authorization and individuals who entered the country lawfully and stayed after their visa or status expired). The higher uninsured rate among noncitizens reflects not only limited access to employer-sponsored coverage but includes immigrant eligibility restrictions for federal programs such as Medicaid, the Children’s Health Insurance Program, and the Affordable Care Act Marketplace coverage.⁶⁰

With approximately 9 million Americans living in mixed-status families (and nearly 10% of babies born each year with at least one undocumented parent), restrictive federal or state health care policies may extend beyond their stated target and impact both Latine citizens and noncitizens.^61-65 For instance, Vargas et al⁶⁴ found that both Latine citizens and noncitizens who lived in states with a high number of immigration-related laws had decreased odds of reporting optimal health as compared to Latine respondents in states with fewer immigration-related laws.Other barriers to enrollment include fears and confusion about program qualification, even if eligible.⁵⁸

Medical Mistrust and Unfamiliarity—Mistrust of medical professionals has been shown to reduce patient adherence to treatment as prescribed by their medical provider and can negatively influence health outcomes.⁵³ For racial/ethnic minoritized groups (including Latine/Hispanic patients), medical mistrust may be rooted in patients’ experience of discrimination in the health care setting. In a recent cross-sectional study, results from a survey of California adults (including 704 non-Hispanic Black, 711 Hispanic, and 913 NHW adults) found links between levels of medical mistrust and perceived discrimination based on race/ethnicity and language as well as perceived discrimination due to income level and type or lack of insurance.⁵³ Interestingly, discrimination attributed to income level and insurance status remained after controlling for race/ethnicity and language. As expected, patients reliant on public insurance programs such as Medicare have been reported to have greater medical mistrust and suspicion compared with private insurance holders.⁶⁵ Together, these findings support the notion that individuals who have low socioeconomic status and lack insurance coverage—disproportionately historically marginalized populations—are more likely to perceive discrimination in health care settings, have greater medical mistrust, and experience poorer health outcomes.⁵³

It also is important for health care providers to consider that the US health care system is unfamiliar to many Latine/Hispanic individuals. Costs of medical services tend to be substantially higher in the United States, which can contribute to mistrust in the system.⁶⁶ In addition, unethical medical experimentations have negatively affected both Latine and especially non-Hispanic Black populations, with long-lasting perceptions of deception and exploitation.⁶⁷ These beliefs have undermined the trust that these populations have in clinicians and the health care system.^54,67

Language and Other Cultural Elements—The inability to effectively communicate with health care providers could contribute to disparities in access to and use of health care services among Latine/Hispanic individuals. In a Medical Expenditure Panel Survey analysis, half of Hispanic patients with limited comfort speaking English did not have a usual source of care, and almost 90% of those with a usual source of care had a provider who spoke Spanish or used interpreters—indicating that few Hispanic individuals with limited comfort speaking English selected a usual source of care without language assistance.^68,69 In other examples, language barriers ­contributed to disparities in cancer screening, and individuals with limited English proficiency were more likely to have difficulty understanding their physician due to language barriers.^68,70

Improving cultural misconceptions regarding skin conditions, especially skin cancer, is another important consideration in the Latine/Hispanic community. Many Latine/Hispanic individuals wrongly believe they cannot develop skin cancer due to their darker skin tones and lack of family history.²⁶ Moreover, multiple studies assessing melanoma knowledge and perception among participants with skin of color (including one with an equal number of Latine/Hispanic, Black/African American, and Asian individuals for a total of 120 participants) revealed that many were unaware of the risk for melanoma on acral sites.⁷¹ Participants expressed a need for more culturally relevant content from both clinicians and public materials (eg, images of acral melanoma in a person with skin of color).^71-73

Paucity of Research—There is limited research regarding skin cancer risks and methods of prevention for patients with skin of color, including the Latine/Hispanic population. Efforts to engage and include patients from these communities, as well as clinicians or investigators from similar backgrounds, in clinical studies are desperately needed. It also is important that clinical studies collect data beyond population descriptors to account for both clinical and genetic variations observed in the Latine/Hispanic population. 

Latine/Hispanic individuals are quite diverse with many variable factors that may influence skin cancer outcomes. Often, cancer surveillance data are available in aggregate only, which could mask this heterogeneity.⁷⁴ Rigorous studies that collect more granular data, including objective measures of skin pigmentation beyond self-reported Fitzpatrick skin type, culture/beliefs, lifestyle/behavior, geographic location, socioeconomic status, genetics, or epigenetics could help fully elucidate skin cancer risks and mitigate health disparities among individuals who identify as part of this population.

Final Thoughts

The Latine/Hispanic community—the largest ethnic minoritized group in the United States—is disproportionately affected by dermatologic health disparities. We hope this review helps to increase recognition of the clinical manifestations of skin cancer in Latine/Hispanic patients. Other factors that may impact skin cancer outcomes in this population include (but are not limited to) lack of or inadequate health insurance, medical mistrust, linguistic barriers and/or individual/cultural perspectives, along with limited research. Recognizing and addressing these (albeit complex) barriers that contribute to the inequitable access to health care in this population remains a critical step toward improving skin cancer outcomes.

Many Latine/Hispanic individuals wrongly believe they cannot develop skin cancer due to their darker skin tones and lack of family history.²⁶ Moreover, multiple studies assessing melanoma knowledge and perception among participants with skin of color (including one with an equal number of Latine/Hispanic, Black/African American, and Asian individuals for a total of 120 participants) revealed that many were unaware of the risk for melanoma on acral sites.⁷¹ Participants expressed a need for more culturally relevant content from both clinicians and public materials (eg, images of acral melanoma in a person with skin of color).^71-73

Paucity of Research—There is limited research regarding skin cancer risks and methods of prevention for patients with skin of color, including the Latine/Hispanic population. Efforts to engage and include patients from these communities, as well as clinicians or investigators from similar backgrounds, in clinical studies are desperately needed. It also is important that clinical studies collect data beyond population descriptors to account for both clinical and genetic variations observed in the Latine/Hispanic population. 

Latine/Hispanic individuals are quite diverse with many variable factors that may influence skin cancer outcomes. Often, cancer surveillance data are available in aggregate only, which could mask this heterogeneity.⁷⁴ Rigorous studies that collect more granular data, including objective measures of skin pigmentation beyond self-reported Fitzpatrick skin type, culture/beliefs, lifestyle/behavior, geographic location, socioeconomic status, genetics, or epigenetics could help fully elucidate skin cancer risks and mitigate health disparities among individuals who identify as part of this population.

Final Thoughts

The Latine/Hispanic community—the largest ethnic minoritized group in the United States—is disproportionately affected by dermatologic health disparities. We hope this review helps to increase recognition of the clinical manifestations of skin cancer in Latine/Hispanic patients. Other factors that may impact skin cancer outcomes in this population include (but are not limited to) lack of or inadequate health insurance, medical mistrust, linguistic barriers and/or individual/cultural perspectives, along with limited research. Recognizing and addressing these (albeit complex) barriers that contribute to the inequitable access to health care in this population remains a critical step toward improving skin cancer outcomes.

The Latine/Hispanic population in the United States comprises one of the largest and youngest skin of color communities.^1,2 In 2020, this group accounted for 19% of all Americans—a percentage expected to increase to more than 25% by 2060.³

It must be emphasized that the Latine/Hispanic community in the United States is incredibly diverse.⁴ Approximately one-third of individuals in this group are foreign-born, and this community is made up of people from all racialized groups, religions, languages, and cultural identities.² The heterogeneity of the Latine/Hispanic population translates into a wide representation of skin tones, reflecting a rich range of ancestries, ethnicities, and cultures. The percentage of individuals from each origin group may differ according to where they live in the United States; for instance, individuals who identify as Mexican comprise more than 80% of the Latine/Hispanic population in both Texas and California but only 17% in Florida, where more than half of Latine/Hispanic people identify as Cuban or Puerto Rican.^4,5 As a result, when it comes to skin cancer epidemiology, variations in incidence and mortality may exist within each of these subgroups who identify as part of the Latine/Hispanic community, as reported for other cancers.^6,7 Further research is needed to investigate these potential differences.Unfortunately, considerable health disparities persist among this rapidly growing population, including increased morbidity and mortality from melanoma and keratinocyte carcinomas (KCs) despite overall low lifetime incidence.^8,9 In this review, the epidemiology, clinical manifestation, and ethnic disparities for skin cancer among the US Latine/Hispanic population are summarized; other factors impacting overall health and health care, including sociocultural factors, also are briefly discussed.

Terminology

Before a meaningful dialogue can be had about skin cancer in the Latine/Hispanic population, it is important to contextualize the terms used to identify this patient population, including Latino/Latine and Hispanic. In the early 1970s, the United States adopted the term Hispanic as a way of conglomerating Spanish-speaking individuals from Spain, the Caribbean, and Central and South America. The goal was to implement a common identifier that enabled the US government to study the economic and social development of these groups.¹⁰ Nevertheless, considerable differences (eg, variations in skin pigmentation, sun sensitivity) exist among Hispanic communities, with some having stronger European, African, or Amerindian influences due to colonization of their ­distinct countries.¹¹

In contrast, Latino is a geographic term and refers to people with roots in Latin America and the Caribbean (Table 1).^12,13 For example, a person from Brazil may be considered Latino but not Hispanic as Brazilians speak Portuguese; alternatively, Spaniards (who are considered Hispanic) are not Latino because Spain is not a Latin American country. A person from Mexico would be considered both Latino and Hispanic.¹³

Melanoma

Melanoma, the deadliest form of skin cancer, is more likely to metastasize compared to other forms of skin cancer, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). For Latine/Hispanic individuals living in the United States, the lifetime risk for melanoma is 1 in 200 compared to 1 in 33 for NHW individuals.¹⁴ While the lifetime risk for melanoma is low for the Latine/Hispanic population, Hispanic individuals are diagnosed with melanoma at an earlier age (mean, 56 years), and the rate of new cases is marginally higher for women (4.9 per 100,000) compared to men (4.8 per 100,000).^15,16

Typical sites of melanoma manifestation in Latine/Hispanic individuals include the torso (most common site in Hispanic men), lower extremities (most common site in Hispanic women), and acral sites (palms, soles, and nails).^9,16,17 Anatomic location also can vary according to age for both men and women. For men, the incidence of melanoma on the trunk appears to decrease with age, while the incidence on the head and neck may increase. For women, the incidence of melanoma on the lower extremities and hip increases with age. Cutaneous melanoma may manifest as a lesion with asymmetry, irregular borders, variation in pigmentation, large diameter (>6 mm), and evolution over time. In patients with skin of color, melanoma easily can be missed, as it also typically mimics more benign skin conditions and may develop from an existing black- or dark brown–­pigmented macule.¹⁸ The most common histologic subtype reported among Latine/Hispanic individuals in the United States is superficial spreading melanoma (20%–23%) followed by nodular melanoma and acral lentiginous melanoma.^16,19 Until additional risk factors associated with melanoma susceptibility in Hispanic/Latine people are better elucidated, it may be appropriate to use an alternative acronym, such as CUBED (Table 2), in addition to the standard ABCDE system to help recognize potential melanoma on acral sites.¹⁸

Keratinocyte Carcinomas

Keratinocyte carcinomas, also known as nonmelanoma skin cancers, include BCC and SCC. In comparison to the high-quality data available for melanoma from cancer registries, there are less reliable incidence data for KCs, especially among individuals with skin of color.²⁵ As a result, KC epidemiology in the United States is drawn largely from case series (especially for individuals with skin of color) or claims data from small data sets often from geographically restricted regions within the United States.^25,26

Basal Cell Carcinoma—Basal cell carcinoma is the most common malignant skin cancer in Latine/Hispanic individuals. Among those with lighter skin tones, the lifetime risk for BCC is about 30%.^27,28 Men typically are affected at a higher rate than women, and the median age for diagnosis is 68 years.²⁹ The development of BCC primarily is linked to lifetime accumulated UV radiation exposure. Even though BCC has a low mortality rate, it can lead to substantial morbidity due to factors such as tumor location, size, and rate of invasion, resulting in cosmetic and functional issues. Given its low metastatic potential, treatment of BCC typically is aimed at local control.³⁰ Options for treatment include Mohs micrographic surgery (MMS), curettage and electrodessication, cryosurgery, photodynamic therapy, radiation therapy, and topical therapies. Systemic therapies are reserved for patients with locally advanced or metastatic disease.³⁰

Latine/Hispanic patients characteristically present with BCCs on sun-exposed areas of the skin such as the head and neck region. In most patients, BCC manifests as a translucent pearly nodule with superficial telangiectasias and/or a nonhealing ulcer with a central depression and rolled nontender borders. However, in patients with skin of color, 66% of BCCs manifest with pigmentation; in fact, pigmented BCC (a subtype of BCC) has been shown to have a higher prevalence among Hispanic individuals, with an incidence twice as frequent as in NHW individuals.³¹ In addition, there are reports of increased tendency among Latine/Hispanic individuals to develop multiple BCCs.^32,33

The relationship between UV exposure and KCs could explain the relatively higher incidence in populations with skin of color living in warmer climates, including Hispanic individuals.³⁴ Even so, the development of BCCs appears to correlate directly with the degree of pigmentation in the skin, as it is most common in individuals with lighter skin tones within the Hispanic population.^25,34,35 Other risk factors associated with BCC development include albinism, arsenic ingestion, chronic infections, immunosuppression, history of radiation treatment, and history of scars or ulcers due to physical/thermal trauma.^35-37

Squamous Cell Carcinoma—Squamous cell carcinoma is the second most common skin cancer among Latine/Hispanic patients. In contrast with NHW patients, evidence supporting the role of UV exposure as a primary risk factor for SCC in patients with skin of color remains limited.^25,38 Reports linking UV exposure and KCs in Hispanic and Black individuals predominantly include case series or population-based studies that do not consider levels of UV exposure.²⁵

More recently, genetic ancestry analyses of a large multiethnic cohort found an increased risk for cutaneous SCC among Latine/Hispanic individuals with European ancestry compared to those with Native American or African ancestry; however, these genetic ancestry associations were attenuated (although not eliminated) after considering skin pigmentation (using loci associated with skin pigmentation), history of sun exposure (using actinic keratoses as a covariate for chronic sun exposure), and sun-protected vs sun-exposed anatomic sites, supporting the role of other environmental or sociocultural factors in the development of SCC.³⁹ Similar to BCCs, immunosuppression, chronic scarring, skin irritation, and inflammatory disease also are documented risk factors.^9,32

Among NHW individuals with lighter skin tones, SCC characteristically manifests on sun-exposed areas of the skin such as the head and neck region. Typically, a lesion may appear as a scaly erythematous papule or plaque that may be verrucous in nature or a nonhealing bleeding ulcer. In patients with more deeply pigmented skin, SCC tends to develop in the perianal region and on the penis and lower legs; pigmented lesions also may be present (as commonly reported in BCCs).^9,32,36

Unfortunately, the lower incidence of KCs and lack of surveillance in populations with skin of color result in a low index of clinical suspicion, leading to delayed diagnoses and increased morbidity.⁴⁰ Keratinocyte carcinomas are more costly to treat and require more health care resources for Latine/Hispanic and Black patients compared to their NHW counterparts; for example, KCs are associated with more ambulatory visits, more prescription medications, and greater cost on a per-person, per-year basis in Latine/Hispanic and Black patients compared with NHW patients.⁴¹ Moreover, a recent multicenter retrospective study found Hispanic patients had 17% larger MMS defects following treatment for KCs compared to NHW patients after adjustment for age, sex, and insurance type.⁴²

Hispanic patients tend to present initially with SCCs in areas associated with advanced disease, such as the anogenital region, penis, and the lower extremities. Latine and Black men have the highest incidence of penile SCC, which is rare with high morbidity and mortality.^32,43,44 The higher incidence of penile SCC among Hispanic individuals living in southern states could correspond to circumcision or HPV infection rates,⁴⁴ ultimately impacting incidence.⁴⁵

Dermatofibrosarcoma Protuberans

Dermatofibrosarcoma protuberans (DFSP) is a rare locally aggressive cutaneous sarcoma. According to population studies, overall incidence of DFSP is around 4.1 to 4.2 per million in the United States. Population-based studies on DFSP are limited, but available data suggest that Black patients as well as women have the highest incidence.⁴⁶

Dermatofibrosarcoma protuberans is characterized by its capacity to invade surrounding tissues in a tentaclelike pattern.⁴⁷ This characteristic often leads to inadequate initial resection of the lesion as well as a high recurrence rate despite its low metastatic potential.⁴⁸ In early stages, DFSP typically manifests as an asymptomatic plaque with a slow growth rate. The color of the lesion ranges from reddish brown to flesh colored. The pigmented form of DFSP, known as Bednar tumor, is the most common among Black patients.⁴⁷ As the tumor grows, it tends to become firm and nodular. The most common location for DFSP is on the trunk or the upper and lower extremities.⁴⁷

Although current guidelines designate MMS as the first-line treatment for DFSP, the procedure may be inaccessible for certain populations.⁴⁹ Patients with skin of color are more likely to undergo wide local excision (WLE) than MMS; however, WLE is less effective, with a recurrence rate of 30% compared with 3% in those treated with MMS.⁵⁰ A retrospective cohort study of more than 2000 patients revealed that Hispanic and Black patients were less likely to undergo MMS. In addition, the authors noted that WLE recipients more commonly were deceased at the end of the study.⁵¹

Despite undergoing treatment for a primary DFSP, Hispanic patients also appear to be at increased risk for a second surgery.⁵² Additional studies are needed to elucidate the reasons behind higher recurrence rates in Latine/Hispanic patients compared to NHW individuals.

Factors Influencing Skin Cancer Outcomes

In recent years, racial and ethnic disparities in health care use, medical treatment, and quality of care among minoritized populations (including Latine/Hispanic groups) have been documented in the medical literature.^53,54 These systemic inequities, which are rooted in structural racism,⁵⁵ have contributed to poorer health outcomes, worse health status, and lower-quality care for minoritized patients living in the United States, including those impacted by dermatologic conditions.^8,43,55-57 Becoming familiar with the sociocultural factors influencing skin cancer outcomes in the Latine/Hispanic community (including the lack of or inadequate health insurance, medical mistrust, language, and other cultural elements) and the paucity of research in this domain could help eliminate existing health inequities in this population.

Health Insurance Coverage—Although the uninsured rates in the Latine population have decreased since the passage of the Affordable Care Act (from 30% in 2013 to a low of 19% in 2017),⁵⁸ inadequate health insurance coverage remains one of the largest barriers to health care access and a contributor to health disparities among the Latine community. Nearly 1 in 5 Latine individuals in the United States are uninsured compared to 8% of NHW individuals.⁵⁸ Even though Latine individuals are more likely than non-Latine individuals to be part of the workforce, Latine employees are less likely to receive employer-sponsored coverage (27% vs 53% for NHW individuals).⁵⁹

Not surprisingly, noncitizens are far less likely to be insured; this includes lawfully present immigrants (ie, permanent residents or green card holders, refugees, asylees, and others who are authorized to live in the United States temporarily or permanently) and undocumented immigrants (including individuals who entered the country without authorization and individuals who entered the country lawfully and stayed after their visa or status expired). The higher uninsured rate among noncitizens reflects not only limited access to employer-sponsored coverage but includes immigrant eligibility restrictions for federal programs such as Medicaid, the Children’s Health Insurance Program, and the Affordable Care Act Marketplace coverage.⁶⁰

With approximately 9 million Americans living in mixed-status families (and nearly 10% of babies born each year with at least one undocumented parent), restrictive federal or state health care policies may extend beyond their stated target and impact both Latine citizens and noncitizens.^61-65 For instance, Vargas et al⁶⁴ found that both Latine citizens and noncitizens who lived in states with a high number of immigration-related laws had decreased odds of reporting optimal health as compared to Latine respondents in states with fewer immigration-related laws.Other barriers to enrollment include fears and confusion about program qualification, even if eligible.⁵⁸

Medical Mistrust and Unfamiliarity—Mistrust of medical professionals has been shown to reduce patient adherence to treatment as prescribed by their medical provider and can negatively influence health outcomes.⁵³ For racial/ethnic minoritized groups (including Latine/Hispanic patients), medical mistrust may be rooted in patients’ experience of discrimination in the health care setting. In a recent cross-sectional study, results from a survey of California adults (including 704 non-Hispanic Black, 711 Hispanic, and 913 NHW adults) found links between levels of medical mistrust and perceived discrimination based on race/ethnicity and language as well as perceived discrimination due to income level and type or lack of insurance.⁵³ Interestingly, discrimination attributed to income level and insurance status remained after controlling for race/ethnicity and language. As expected, patients reliant on public insurance programs such as Medicare have been reported to have greater medical mistrust and suspicion compared with private insurance holders.⁶⁵ Together, these findings support the notion that individuals who have low socioeconomic status and lack insurance coverage—disproportionately historically marginalized populations—are more likely to perceive discrimination in health care settings, have greater medical mistrust, and experience poorer health outcomes.⁵³

It also is important for health care providers to consider that the US health care system is unfamiliar to many Latine/Hispanic individuals. Costs of medical services tend to be substantially higher in the United States, which can contribute to mistrust in the system.⁶⁶ In addition, unethical medical experimentations have negatively affected both Latine and especially non-Hispanic Black populations, with long-lasting perceptions of deception and exploitation.⁶⁷ These beliefs have undermined the trust that these populations have in clinicians and the health care system.^54,67

Language and Other Cultural Elements—The inability to effectively communicate with health care providers could contribute to disparities in access to and use of health care services among Latine/Hispanic individuals. In a Medical Expenditure Panel Survey analysis, half of Hispanic patients with limited comfort speaking English did not have a usual source of care, and almost 90% of those with a usual source of care had a provider who spoke Spanish or used interpreters—indicating that few Hispanic individuals with limited comfort speaking English selected a usual source of care without language assistance.^68,69 In other examples, language barriers ­contributed to disparities in cancer screening, and individuals with limited English proficiency were more likely to have difficulty understanding their physician due to language barriers.^68,70

Improving cultural misconceptions regarding skin conditions, especially skin cancer, is another important consideration in the Latine/Hispanic community. Many Latine/Hispanic individuals wrongly believe they cannot develop skin cancer due to their darker skin tones and lack of family history.²⁶ Moreover, multiple studies assessing melanoma knowledge and perception among participants with skin of color (including one with an equal number of Latine/Hispanic, Black/African American, and Asian individuals for a total of 120 participants) revealed that many were unaware of the risk for melanoma on acral sites.⁷¹ Participants expressed a need for more culturally relevant content from both clinicians and public materials (eg, images of acral melanoma in a person with skin of color).^71-73

Paucity of Research—There is limited research regarding skin cancer risks and methods of prevention for patients with skin of color, including the Latine/Hispanic population. Efforts to engage and include patients from these communities, as well as clinicians or investigators from similar backgrounds, in clinical studies are desperately needed. It also is important that clinical studies collect data beyond population descriptors to account for both clinical and genetic variations observed in the Latine/Hispanic population. 

Latine/Hispanic individuals are quite diverse with many variable factors that may influence skin cancer outcomes. Often, cancer surveillance data are available in aggregate only, which could mask this heterogeneity.⁷⁴ Rigorous studies that collect more granular data, including objective measures of skin pigmentation beyond self-reported Fitzpatrick skin type, culture/beliefs, lifestyle/behavior, geographic location, socioeconomic status, genetics, or epigenetics could help fully elucidate skin cancer risks and mitigate health disparities among individuals who identify as part of this population.

Final Thoughts

The Latine/Hispanic community—the largest ethnic minoritized group in the United States—is disproportionately affected by dermatologic health disparities. We hope this review helps to increase recognition of the clinical manifestations of skin cancer in Latine/Hispanic patients. Other factors that may impact skin cancer outcomes in this population include (but are not limited to) lack of or inadequate health insurance, medical mistrust, linguistic barriers and/or individual/cultural perspectives, along with limited research. Recognizing and addressing these (albeit complex) barriers that contribute to the inequitable access to health care in this population remains a critical step toward improving skin cancer outcomes.

Diversity, equity, and inclusion (DEI) programs seek to improve dermatologic education and clinical care for an increasingly diverse patient population as well as to recruit and sustain a physician workforce that reflects the diversity of the patients they serve.^1,2 In dermatology, only 4.2% and 3.0% of practicing dermatologists self-identify as being of Hispanic and African American ethnicity, respectively, compared with 18.5% and 13.4% of the general population, respectively.³ Creating an educational system that works to meet the goals of DEI is essential to improve health outcomes and address disparities. The lack of robust DEI-related curricula during residency training may limit the ability of practicing dermatologists to provide comprehensive and culturally sensitive care. It has been shown that racial concordance between patients and physicians has a positive impact on patient satisfaction by fostering a trusting patient-physician relationship.⁴

It is the responsibility of all dermatologists to create an environment where patients from any background can feel comfortable, which can be cultivated by establishing patient-centered communication and cultural humility.⁵ These skills can be strengthened via the implementation of DEI-related curricula during residency training. Augmenting exposure of these topics during training can optimize the delivery of dermatologic care by providing residents with the tools and confidence needed to care for patients of culturally diverse backgrounds. Enhancing DEI education is crucial to not only improve the recognition and treatment of dermatologic conditions in all skin and hair types but also to minimize misconceptions, stigma, health disparities, and discrimination faced by historically marginalized communities. Creating a culture of inclusion is of paramount importance to build successful relationships with patients and colleagues of culturally diverse backgrounds.⁶

There are multiple efforts underway to increase DEI education across the field of dermatology, including the development of DEI task forces in professional organizations and societies that serve to expand DEI-related research, mentorship, and education. The American Academy of Dermatology has been leading efforts to create a curriculum focused on skin of color, particularly addressing inadequate educational training on how dermatologic conditions manifest in this population.⁷ The Skin of Color Society has similar efforts underway and is developing a speakers bureau to give leading experts a platform to lecture dermatology trainees as well as patient and community audiences on various topics in skin of color.⁸ These are just 2 of many professional dermatology organizations that are advocating for expanded education on DEI; however, consistently integrating DEI-related topics into dermatology residency training curricula remains a gap in pedagogy. To identify the DEI-related topics of greatest relevance to the dermatology resident curricula, we implemented a modified electronic Delphi (e-Delphi) consensus process to provide standardized recommendations.

Methods

A 2-round modified e-Delphi method was utilized (Figure). An initial list of potential curricular topics was formulated by an expert panel consisting of 5 dermatologists from the Association of Professors of Dermatology DEI subcommittee and the American Academy of Dermatology Diversity Task Force (A.M.A., S.B., R.V., S.D.W., J.I.S.). Initial topics were selected via several meetings among the panel members to discuss existing DEI concerns and issues that were deemed relevant due to education gaps in residency training. The list of topics was further expanded with recommendations obtained via an email sent to dermatology program directors on the Association of Professors of Dermatology listserve, which solicited voluntary participation of academic dermatologists, including program directors and dermatology residents.

There were 2 voting rounds, with each round consisting of questions scored on a Likert scale ranging from 1 to 5 (1=not essential, 2=probably not essential, 3=neutral, 4=probably essential, 5=definitely essential). The inclusion criteria to classify a topic as necessary for integration into the dermatology residency curriculum included 95% (18/19) or more of respondents rating the topic as probably essential or definitely essential; if more than 90% (17/19) of respondents rated the topic as probably essential or definitely essential and less than 10% (2/19) rated it as not essential or probably not essential, the topic was still included as part of the suggested curriculum. Topics that received ratings of probably essential or definitely essential by less than 80% (15/19) of respondents were removed from consideration. The topics that did not meet inclusion or exclusion criteria during the first round of voting were refined by the e-Delphi steering committee (V.S.E-C. and F-A.R.) based on open-ended feedback from the voting group provided at the end of the survey and subsequently passed to the second round of voting.

Results

Participants—A total of 19 respondents participated in both voting rounds, the majority (80% [15/19]) of whom were program directors or dermatologists affiliated with academia or development of DEI education; the remaining 20% [4/19]) were dermatology residents.

Open-Ended Feedback—Voting group members were able to provide open-ended feedback for each of the sets of topics after the survey, which the steering committee utilized to modify the topics as needed for the final voting round. For example, “structural racism/discrimination” was originally mentioned as a topic, but several participants suggested including specific types of racism; therefore, the wording was changed to “racism: types, definitions” to encompass broader definitions and types of racism.

Survey Results—Two genres of topics were surveyed in each voting round: clinical and nonclinical. Participants voted on a total of 61 topics, with 23 ultimately selected in the final list of consensus curricular topics. Of those, 9 were clinical and 14 nonclinical. All topics deemed necessary for inclusion in residency curricula are presented in eTables 1 and 2.

During the first round of voting, the e-Delphi panel reached a consensus to include the following 17 topics as essential to dermatology residency training (along with the percentage of voters who classified them as probably essential or definitely essential): how to mitigate bias in clinical and workplace settings (100% [40/40]); social determinants of health-related disparities in dermatology (100% [40/40]); hairstyling practices across different hair textures (100% [40/40]); definitions and examples of microaggressions (97.50% [39/40]); definition, background, and types of bias (97.50% [39/40]); manifestations of bias in the clinical setting (97.44% [38/39]); racial and ethnic disparities in dermatology (97.44% [38/39]); keloids (97.37% [37/38]); differences in dermoscopic presentations in skin of color (97.30% [36/37]); skin cancer in patients with skin of color (97.30% [36/37]); disparities due to bias (95.00% [38/40]); how to apply cultural humility and safety to patients of different cultural backgrounds (94.87% [37/40]); best practices in providing care to patients with limited English proficiency (94.87% [37/40]); hair loss in patients with textured hair (94.74% [36/38]); pseudofolliculitis barbae and acne keloidalis nuchae (94.60% [35/37]); disparities regarding people experiencing homelessness (92.31% [36/39]); and definitions and types of racism and other forms of discrimination (92.31% [36/39]). eTable 1 provides a list of suggested resources to incorporate these topics into the educational components of residency curricula. The resources provided were not part of the voting process, and they were not considered in the consensus analysis; they are included here as suggested educational catalysts.

During the second round of voting, 25 topics were evaluated. Of those, the following 6 topics were proposed to be included as essential in residency training: differences in prevalence and presentation of common inflammatory disorders (100% [29/29]); manifestations of bias in the learning environment (96.55%); antiracist action and how to decrease the effects of structural racism in clinical and educational settings (96.55% [28/29]); diversity of images in dermatology education (96.55% [28/29]); pigmentary disorders and their psychological effects (96.55% [28/29]); and LGBTQ (lesbian, gay, bisexual, transgender, and queer) dermatologic health care (96.55% [28/29]). eTable 2 includes these topics as well as suggested resources to help incorporate them into training.

Comment

This study utilized a modified e-Delphi technique to identify relevant clinical and nonclinical DEI topics that should be incorporated into dermatology residency curricula. The panel members reached a consensus for 9 clinical DEI-related topics. The respondents agreed that the topics related to skin and hair conditions in patients with skin of color as well as textured hair were crucial to residency education. Skin cancer, hair loss, pseudofolliculitis barbae, acne keloidalis nuchae, keloids, pigmentary disorders, and their varying presentations in patients with skin of color were among the recommended topics. The panel also recommended educating residents on the variable visual presentations of inflammatory conditions in skin of color. Addressing the needs of diverse patients—for example, those belonging to the LGBTQ community—also was deemed important for inclusion.

The remaining 14 chosen topics were nonclinical items addressing concepts such as bias and health care disparities as well as cultural humility and safety.⁹ Cultural humility and safety focus on developing cultural awareness by creating a safe setting for patients rather than encouraging power relationships between them and their physicians. Various topics related to racism also were recommended to be included in residency curricula, including education on implementation of antiracist action in the workplace.

Many of the nonclinical topics are intertwined; for instance, learning about health care disparities in patients with limited English proficiency allows for improved best practices in delivering care to patients from this population. The first step in overcoming bias and subsequent disparities is acknowledging how the perpetuation of bias leads to disparities after being taught tools to recognize it.

Our group’s guidance on DEI topics should help dermatology residency program leaders as they design and refine program curricula. There are multiple avenues for incorporating education on these topics, including lectures, interactive workshops, role-playing sessions, book or journal clubs, and discussion circles. Many of these topics/programs may already be included in programs’ didactic curricula, which would minimize the burden of finding space to educate on these topics. Institutional cultural change is key to ensuring truly diverse, equitable, and inclusive workplaces. Educating tomorrow’s dermatologists on these topics is a first step toward achieving that cultural change.

Limitations—A limitation of this e-Delphi survey is that only a selection of experts in this field was included. Additionally, we were concerned that the Likert scale format and the bar we set for inclusion and exclusion may have failed to adequately capture participants’ nuanced opinions. As such, participants were able to provide open-ended feedback, and suggestions for alternate wording or other changes were considered by the steering committee. Finally, inclusion recommendations identified in this survey were developed specifically for US dermatology residents.

Conclusion

In this e-Delphi consensus assessment of DEI-related topics, we recommend the inclusion of 23 topics into dermatology residency program curricula to improve medical training and the patient-physician relationship as well as to create better health outcomes. We also provide specific sample resource recommendations in eTables 1 and 2 to facilitate inclusion of these topics into residency curricula across the country.

There were 2 voting rounds, with each round consisting of questions scored on a Likert scale ranging from 1 to 5 (1=not essential, 2=probably not essential, 3=neutral, 4=probably essential, 5=definitely essential). The inclusion criteria to classify a topic as necessary for integration into the dermatology residency curriculum included 95% (18/19) or more of respondents rating the topic as probably essential or definitely essential; if more than 90% (17/19) of respondents rated the topic as probably essential or definitely essential and less than 10% (2/19) rated it as not essential or probably not essential, the topic was still included as part of the suggested curriculum. Topics that received ratings of probably essential or definitely essential by less than 80% (15/19) of respondents were removed from consideration. The topics that did not meet inclusion or exclusion criteria during the first round of voting were refined by the e-Delphi steering committee (V.S.E-C. and F-A.R.) based on open-ended feedback from the voting group provided at the end of the survey and subsequently passed to the second round of voting.

Results

Participants—A total of 19 respondents participated in both voting rounds, the majority (80% [15/19]) of whom were program directors or dermatologists affiliated with academia or development of DEI education; the remaining 20% [4/19]) were dermatology residents.

Open-Ended Feedback—Voting group members were able to provide open-ended feedback for each of the sets of topics after the survey, which the steering committee utilized to modify the topics as needed for the final voting round. For example, “structural racism/discrimination” was originally mentioned as a topic, but several participants suggested including specific types of racism; therefore, the wording was changed to “racism: types, definitions” to encompass broader definitions and types of racism.

Survey Results—Two genres of topics were surveyed in each voting round: clinical and nonclinical. Participants voted on a total of 61 topics, with 23 ultimately selected in the final list of consensus curricular topics. Of those, 9 were clinical and 14 nonclinical. All topics deemed necessary for inclusion in residency curricula are presented in eTables 1 and 2.

During the first round of voting, the e-Delphi panel reached a consensus to include the following 17 topics as essential to dermatology residency training (along with the percentage of voters who classified them as probably essential or definitely essential): how to mitigate bias in clinical and workplace settings (100% [40/40]); social determinants of health-related disparities in dermatology (100% [40/40]); hairstyling practices across different hair textures (100% [40/40]); definitions and examples of microaggressions (97.50% [39/40]); definition, background, and types of bias (97.50% [39/40]); manifestations of bias in the clinical setting (97.44% [38/39]); racial and ethnic disparities in dermatology (97.44% [38/39]); keloids (97.37% [37/38]); differences in dermoscopic presentations in skin of color (97.30% [36/37]); skin cancer in patients with skin of color (97.30% [36/37]); disparities due to bias (95.00% [38/40]); how to apply cultural humility and safety to patients of different cultural backgrounds (94.87% [37/40]); best practices in providing care to patients with limited English proficiency (94.87% [37/40]); hair loss in patients with textured hair (94.74% [36/38]); pseudofolliculitis barbae and acne keloidalis nuchae (94.60% [35/37]); disparities regarding people experiencing homelessness (92.31% [36/39]); and definitions and types of racism and other forms of discrimination (92.31% [36/39]). eTable 1 provides a list of suggested resources to incorporate these topics into the educational components of residency curricula. The resources provided were not part of the voting process, and they were not considered in the consensus analysis; they are included here as suggested educational catalysts.

During the second round of voting, 25 topics were evaluated. Of those, the following 6 topics were proposed to be included as essential in residency training: differences in prevalence and presentation of common inflammatory disorders (100% [29/29]); manifestations of bias in the learning environment (96.55%); antiracist action and how to decrease the effects of structural racism in clinical and educational settings (96.55% [28/29]); diversity of images in dermatology education (96.55% [28/29]); pigmentary disorders and their psychological effects (96.55% [28/29]); and LGBTQ (lesbian, gay, bisexual, transgender, and queer) dermatologic health care (96.55% [28/29]). eTable 2 includes these topics as well as suggested resources to help incorporate them into training.

Comment

This study utilized a modified e-Delphi technique to identify relevant clinical and nonclinical DEI topics that should be incorporated into dermatology residency curricula. The panel members reached a consensus for 9 clinical DEI-related topics. The respondents agreed that the topics related to skin and hair conditions in patients with skin of color as well as textured hair were crucial to residency education. Skin cancer, hair loss, pseudofolliculitis barbae, acne keloidalis nuchae, keloids, pigmentary disorders, and their varying presentations in patients with skin of color were among the recommended topics. The panel also recommended educating residents on the variable visual presentations of inflammatory conditions in skin of color. Addressing the needs of diverse patients—for example, those belonging to the LGBTQ community—also was deemed important for inclusion.

The remaining 14 chosen topics were nonclinical items addressing concepts such as bias and health care disparities as well as cultural humility and safety.⁹ Cultural humility and safety focus on developing cultural awareness by creating a safe setting for patients rather than encouraging power relationships between them and their physicians. Various topics related to racism also were recommended to be included in residency curricula, including education on implementation of antiracist action in the workplace.

Many of the nonclinical topics are intertwined; for instance, learning about health care disparities in patients with limited English proficiency allows for improved best practices in delivering care to patients from this population. The first step in overcoming bias and subsequent disparities is acknowledging how the perpetuation of bias leads to disparities after being taught tools to recognize it.

Our group’s guidance on DEI topics should help dermatology residency program leaders as they design and refine program curricula. There are multiple avenues for incorporating education on these topics, including lectures, interactive workshops, role-playing sessions, book or journal clubs, and discussion circles. Many of these topics/programs may already be included in programs’ didactic curricula, which would minimize the burden of finding space to educate on these topics. Institutional cultural change is key to ensuring truly diverse, equitable, and inclusive workplaces. Educating tomorrow’s dermatologists on these topics is a first step toward achieving that cultural change.

Limitations—A limitation of this e-Delphi survey is that only a selection of experts in this field was included. Additionally, we were concerned that the Likert scale format and the bar we set for inclusion and exclusion may have failed to adequately capture participants’ nuanced opinions. As such, participants were able to provide open-ended feedback, and suggestions for alternate wording or other changes were considered by the steering committee. Finally, inclusion recommendations identified in this survey were developed specifically for US dermatology residents.

Conclusion

In this e-Delphi consensus assessment of DEI-related topics, we recommend the inclusion of 23 topics into dermatology residency program curricula to improve medical training and the patient-physician relationship as well as to create better health outcomes. We also provide specific sample resource recommendations in eTables 1 and 2 to facilitate inclusion of these topics into residency curricula across the country.

Diversity, equity, and inclusion (DEI) programs seek to improve dermatologic education and clinical care for an increasingly diverse patient population as well as to recruit and sustain a physician workforce that reflects the diversity of the patients they serve.^1,2 In dermatology, only 4.2% and 3.0% of practicing dermatologists self-identify as being of Hispanic and African American ethnicity, respectively, compared with 18.5% and 13.4% of the general population, respectively.³ Creating an educational system that works to meet the goals of DEI is essential to improve health outcomes and address disparities. The lack of robust DEI-related curricula during residency training may limit the ability of practicing dermatologists to provide comprehensive and culturally sensitive care. It has been shown that racial concordance between patients and physicians has a positive impact on patient satisfaction by fostering a trusting patient-physician relationship.⁴

It is the responsibility of all dermatologists to create an environment where patients from any background can feel comfortable, which can be cultivated by establishing patient-centered communication and cultural humility.⁵ These skills can be strengthened via the implementation of DEI-related curricula during residency training. Augmenting exposure of these topics during training can optimize the delivery of dermatologic care by providing residents with the tools and confidence needed to care for patients of culturally diverse backgrounds. Enhancing DEI education is crucial to not only improve the recognition and treatment of dermatologic conditions in all skin and hair types but also to minimize misconceptions, stigma, health disparities, and discrimination faced by historically marginalized communities. Creating a culture of inclusion is of paramount importance to build successful relationships with patients and colleagues of culturally diverse backgrounds.⁶

There are multiple efforts underway to increase DEI education across the field of dermatology, including the development of DEI task forces in professional organizations and societies that serve to expand DEI-related research, mentorship, and education. The American Academy of Dermatology has been leading efforts to create a curriculum focused on skin of color, particularly addressing inadequate educational training on how dermatologic conditions manifest in this population.⁷ The Skin of Color Society has similar efforts underway and is developing a speakers bureau to give leading experts a platform to lecture dermatology trainees as well as patient and community audiences on various topics in skin of color.⁸ These are just 2 of many professional dermatology organizations that are advocating for expanded education on DEI; however, consistently integrating DEI-related topics into dermatology residency training curricula remains a gap in pedagogy. To identify the DEI-related topics of greatest relevance to the dermatology resident curricula, we implemented a modified electronic Delphi (e-Delphi) consensus process to provide standardized recommendations.

Methods

A 2-round modified e-Delphi method was utilized (Figure). An initial list of potential curricular topics was formulated by an expert panel consisting of 5 dermatologists from the Association of Professors of Dermatology DEI subcommittee and the American Academy of Dermatology Diversity Task Force (A.M.A., S.B., R.V., S.D.W., J.I.S.). Initial topics were selected via several meetings among the panel members to discuss existing DEI concerns and issues that were deemed relevant due to education gaps in residency training. The list of topics was further expanded with recommendations obtained via an email sent to dermatology program directors on the Association of Professors of Dermatology listserve, which solicited voluntary participation of academic dermatologists, including program directors and dermatology residents.

Topics that received ratings of probably essential or definitely essential by less than 80% (15/19) of respondents were removed from consideration. The topics that did not meet inclusion or exclusion criteria during the first round of voting were refined by the e-Delphi steering committee (V.S.E-C. and F-A.R.) based on open-ended feedback from the voting group provided at the end of the survey and subsequently passed to the second round of voting.
