Mpox: Dermatology registry data pinpoints unique signs
that frequently appeared before systemic illness and a much lower overall numbers of lesions.
“Just these two findings alone show how important it is to remain clinically vigilant as dermatologists,” Esther Freeman, MD, PhD, director of global health dermatology at Massachusetts General Hospital, Boston, said in an interview. She is the corresponding author of the study, which analyzed 101 mpox cases from 13 countries and was published online on in the Journal of the American Academy of Dermatology.
“Mpox appeared to manifest differently than in previous outbreaks with morphologic and clinical evolutions much different than previously reported in endemic and prior outbreaks,” added Dr. Freeman. “Dermatologists should continue to keep mpox on the differential as it continues to circulate at low levels in the population and is a mimicker of many other common skin diseases.”
According to the Centers for Disease Control and Prevention, as of Jan. 20, 2023, there have been 30,061 cases of mpox in the United States during the outbreak that began in 2022; 23 people died. Worldwide, the number of cases neared 85,000.
Most of the affected cases were among gay, bisexual, and other men who have sex with men. A vaccination effort began last summer, and the number of cases soon plummeted. The national daily case count in January has been in the single digits.
For the new report, dermatologists tracked cases via the American Academy of Dermatology/International League of Dermatologic Societies (AAD/ILDS) Dermatology COVID-19, Monkeypox (mpox), and Emerging Infections Registry. The new report includes data about cases entered from Aug. 4 to Nov. 13. Of these cases, 97% were male, median age was 35 years, 62% were White, 20% were Hispanic, and 11% were Black.
Just over half (54%) of patients reported skin lesions as the first sign of disease, while others had signs such as fever (16%) and malaise (9%). “This is a sharp contrast to endemic or prior outbreaks in which a ‘flu-like’ prodrome preceded lesions,” Dr. Freeman said. “Dermatologists should be aware that patients may come in with mpox skin lesions as their only initial symptoms.”
In contrast to past outbreaks where patients may have had dozens or hundreds of lesions, 20% had only 1 lesion, while 52% had 2-5 lesions, and 20% had 6-20 lesions. “There may be only a few lesions, so index of suspicion needs to be high,” Dr. Freeman said.
According to the study, “the most common skin lesion morphologies and secondary characteristics reported included papules, vesicles/blisters, pustules, erosions/ulcers and crust/scabs.” Dr. Freeman cautioned that “lesions may not go through the ‘typical’ progression from papule to pustule. The initial lesion could even be an ulceration or a crust. For dermatologists, this means you need to have a high index of suspicion, especially if you see a new onset lesion in the groin or perianal area, though they can also start elsewhere.”
She added that “the lesion you see on exam could be a classic pustule/pseudopustule, but it might not be – it could be a small perianal erosion or ulceration. If you have any concern it could be mpox, it’s a good idea to test by PCR.”
Morbilliform rash, scarring reported
The study also highlighted 10 cases of morbilliform rash. “A morbilliform exanthem is pretty nonspecific, and usually cases of mpox have more specific features,” dermatologist and study coauthor Misha Rosenbach, MD, of the University of Pennsylvania, Philadelphia, said in an interview.
“Given the current low rates of mpox, I do not think most dermatologists need to worry about mpox when evaluating morbilliform exanthems. However, in high-risk patients or patients with other morphologies, it is worth noting that there’s a chance that this may be related.”
Emory University dermatologist Howa Yeung, MD, MSc, who wasn’t involved with the study, said in an interview that morbilliform rashes in the mouth/tongue area, mostly on days 1-5, should be considered a possible sign of mpox. “While I didn’t typically think of monkeypox virus as a cause of viral exanthems, I will now add it to my differential diagnoses.”
In the report, 13% of patients had scarring, “an outcome underemphasized in the current literature” that could have long-term emotional and mental effects, the authors noted. “Some patients, particularly immunosuppressed patients, have had very large and/or ulceronecrotic lesions,” Dr. Rosenbach said. “Their scarring can be quite significant. There is, to date, very little guidance for clinicians or patients on how to mitigate this risk and, if scarring is developing, how best to manage it.”
As for lessons from the findings, Dr. Yeung said, “dermatologists need to be aware that patients with mpox can have multiple morphologies at the same time and lesions can skip stages.” And, he pointed out, it’s clear that wound care is important to prevent scarring.
The AAD has a resource page on skin care in patients with mpox that includes information about preventing scarring. Examples of mpox rashes are available on the CDC website.
The study was supported by a grant from the International League of Dermatologic Societies and in-kind support from the American Academy of Dermatology. Dr. Freeman is a coauthor for UpToDate. Dr. Freeman and Dr. Rosenbach are members of the AAD Ad Hoc Task Force to Create Monkeypox Content. Study authors reported no other disclosures, and Dr. Yeung has no disclosures.

Age-related atopic dermatitis phenotypes evaluated in study
, while older adults tend to present with less flexural eczema and the fewest associated signs.
Those are key findings from a study conducted at a single academic medical center, which aimed to identify the age-related clinical phenotypes of AD.
“Previous studies have found differences in the clinical characteristics of AD depending on age of AD onset, ethnic background, and AD severity,” senior author Jonathan I. Silverberg, MD, PhD, MPH, director of clinical research in the department of dermatology at George Washington University, Washington, and his coauthor wrote in the study, which was published online in JAAD International. “However, none have prospectively compared the clinical characteristics and associated signs by age group. Improved understanding of the clinical phenotypes of AD may help guide choice of treatment and improve health outcomes,” they added.
Along with coauthor Sheena Chatrath, a dermatology research fellow in the department, Dr. Silverberg prospectively reviewed self-reported questionnaires that were completed by 380 patients prior to their visit at GWU’s eczema clinic between 2013 and 2019. Questions included age of AD onset, sociodemographics, Visual Analog Scale (VAS) itch and sleep for Scoring AD, and Numeric Rating Scale (NRS) for skin pain and itch. The researchers used the Eczema Area Severity Index to assess AD severity and a dermatologist conducted full body skin exams, noting the distribution of AD involvement as well as associated signs.
Of the 380 patients, 6.1% were younger than aged 18 years, 46.3% were young adults aged 18-39 years, and 47.6% were older adults 40 years of age and older.
Compared with pediatric patients, both young and older adults were less likely to experience AD on the ankles (adjusted odds ratio [aOR], 0.41 and 0.43, respectively), moderate to severe AD lesions on flexures (aOR, 0.47 and 0.30), pityriasis alba (aOR, 0.24 and 0.07), oozing lesions (aOR, 0.44 and 0.35), and moderate to severe excoriations (aOR, 0.49 and 0.44).
In children, severe itch was more common, reported in 47.1%, compared with 43.4% of the young adults and 38.6% of the older adults, and itch was less severe among the young and older adults. “Interestingly, despite increased itch in pediatric patients, we found no difference in the severity of skin pain across all age groups,” the researchers wrote. “Moreover, pediatric patients reported skin pain less often than adult patients. This may be due to age-related differences of pain perception.”
In other findings, compared with pediatric patients, young adults were more likely to experience AD around the eyes (aOR, 2.92), while older adults were less likely to experience AD on elbows (aOR, 0.34), nipples (aOR, 0.40), knees (aOR, 0.27), and less likely to have keratosis pilaris (aOR, 0.38), and lichenification (aOR, 0.47).
Dr. Silverberg and Ms. Chatrath used latent class analysis to identify four classes for distribution of AD lesions. In this model, class 1 had low probabilities of AD involvement at all sites examined and class 2 had low probabilities of scalp, face, and foot involvement, and intermediate probability of all other AD sites. Class 3 had low probabilities of hand and foot involvement, high probability of facial erythema, and intermediate probability of all other AD signs, while class 4 had intermediate probability of postauricular and foot involvement, and high probability of all other AD sites examined.
“Pediatric patients were most commonly in class 4 (33.3%), followed by class 1 and 2 (26.7%), and least commonly in class 3 (13.3%),” the authors wrote. “In young adults, class 4 and 1 were most common (32.4% and 29.4%), followed by class 2 (27.9%), and least commonly class 3 (10.3%). In older adults, class 1 was most common (40.3%), followed by class 4 (23.6%), and least commonly classes 2 and 3 (18.1%).”
The researchers also used latent class analysis to identify four classes for the signs and symptoms of AD. In this model, class 1 had zero-low probability of all AD signs and class 2 had low probability of all AD signs. Class 3 had high probability of oozing lesions and low probability of all other signs, while class 4 had high probability of xerosis, intermediate probability of ichthyosis and palmar hyperlinearity, and low probability of all other AD signs.
In all three groups, the most common class was class 1 (85.6% of older adults, 81.8% of younger adults, and 82.6% of pediatric patients). Among the pediatric patients, they wrote, “class 3 was the second most common (8.7%), followed by class 2 and 4 (4.4%).” Among the young adults, 9.7% were in class 2, 5.7% were in class 4, and 2.8% were in class 3; and among the older adults, 8.3% were in class 4, 4.4% were in class 2, and 1.67% were in class 3.
Zelma Chiesa Fuxench, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, who was asked to comment on the study, said that while AD is traditionally largely thought of as a disease of children primarily involving the flexural areas, “this study provides additional evidence to support that AD is more than just a disease of childhood with a fixed clinical presentation, but is a heterogeneous disease whose clinical presentation varies across different population groups.”
While the study provides insight into the clinical differences that may be observed across AD groups, “care must be taken when interpreting these results as the study was done in a single center with observations collected during one single visit,” she added. “AD is not a ‘static’ disease; its presentation can stay the same in one patient but can vary even in another patient throughout their lifetime. Therefore, studies of a more prospective nature that evaluate the change in clinical presentation using multiple measures throughout time in these individuals would be a step forward to better understand if these phenotypic differences truly exist and, as such, what implications could they have for treatment selection.”
This study was supported by grants from the Agency for Healthcare Research and Quality and the Dermatology Foundation. The researchers reported having no disclosures. Dr. Chiesa Fuxench disclosed serving as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, Pfizer, AbbVie, and Incyte, for which she has received honoraria for AD-related work. She is the recipient of research grants through Regeneron, Sanofi, Tioga, Vanda, Menlo Therapeutics, Leo Pharma, and Eli Lilly for work related to AD as well as honoraria for continuing medical education work related to AD sponsored through educational grants from Regeneron/Sanofi and Pfizer.

Class 3 had high probability of oozing lesions and low probability of all other signs, while class 4 had high probability of xerosis, intermediate probability of ichthyosis and palmar hyperlinearity, and low probability of all other AD signs.
In all three groups, the most common class was class 1 (85.6% of older adults, 81.8% of younger adults, and 82.6% of pediatric patients). Among the pediatric patients, they wrote, “class 3 was the second most common (8.7%), followed by class 2 and 4 (4.4%).” Among the young adults, 9.7% were in class 2, 5.7% were in class 4, and 2.8% were in class 3; and among the older adults, 8.3% were in class 4, 4.4% were in class 2, and 1.67% were in class 3.
Zelma Chiesa Fuxench, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, who was asked to comment on the study, said that while AD is traditionally largely thought of as a disease of children primarily involving the flexural areas, “this study provides additional evidence to support that AD is more than just a disease of childhood with a fixed clinical presentation, but is a heterogeneous disease whose clinical presentation varies across different population groups.”
While the study provides insight into the clinical differences that may be observed across AD groups, “care must be taken when interpreting these results as the study was done in a single center with observations collected during one single visit,” she added. “AD is not a ‘static’ disease; its presentation can stay the same in one patient but can vary even in another patient throughout their lifetime. Therefore, studies of a more prospective nature that evaluate the change in clinical presentation using multiple measures throughout time in these individuals would be a step forward to better understand if these phenotypic differences truly exist and, as such, what implications could they have for treatment selection.”
This study was supported by grants from the Agency for Healthcare Research and Quality and the Dermatology Foundation. The researchers reported having no disclosures. Dr. Chiesa Fuxench disclosed serving as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, Pfizer, AbbVie, and Incyte, for which she has received honoraria for AD-related work. She is the recipient of research grants through Regeneron, Sanofi, Tioga, Vanda, Menlo Therapeutics, Leo Pharma, and Eli Lilly for work related to AD as well as honoraria for continuing medical education work related to AD sponsored through educational grants from Regeneron/Sanofi and Pfizer.

Best estimates made for hydroxychloroquine retinopathy risk
A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.
HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.
Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.
The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.
The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.
Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”
A 2021 joint position statement from the American College of Rheumatology, American Academy of Dermatology, the Rheumatologic Dermatology Society, and the American Academy of Ophthalmology recommends a baseline eye exam within a few months after starting therapy, then additional screening at 5 years on HCQ and annually thereafter.
“Early detection of retinopathy is important in overall visual prognosis, because toxicity can continue even after discontinuation of the medication,” said Rukhsana G. Mirza, MD, professor of ophthalmology and medical education at Northwestern University in Chicago.
“Examination alone is not sufficient to evaluate early changes, and specialized testing must be done. These include color photos, visual field tests, optical coherence tomography, fundus autofluorescence and in some cases, multifocal electroretinogram. Also, the AAO [American Academy of Ophthalmology] has specific recommendations related to Asian patients as they may have a different pattern of retinopathy that must also be considered.”
More accurate risk measurements
This news organization asked study coauthor April Jorge, MD, assistant professor of medicine in the division of rheumatology, allergy, and immunology at Massachusetts General Hospital and Harvard Medical School, Boston, to discuss the study, how it correlates to past research, and what it adds that’s new and useful to rheumatologists and ophthalmologists:
Question: Your research found that a higher dose of HCQ in the first 5 years of treatment led to a greater risk of retinopathy. Is there any indication that a lower dose given more frequently, either within that 5-year period or longer, would pose a similar risk?
Answer: In our study, we assessed the HCQ dose in the first 5 years of use but followed patients who continued the medication longer than 5 years, through up to 15 years of use. Therefore, we compared the risk of HCQ retinopathy associated with different HCQ dosages but for the same duration of use. We found that for any dose of HCQ, the risk of retinopathy increases the longer the medication is used. However, patients who used a higher dose of HCQ had a higher risk of developing retinopathy over time.
Although current guidelines recommend avoiding any HCQ dose over 5 mg/kg per day to reduce the risk of retinopathy, we found a higher risk of retinopathy associated with dosing over 6 mg/kg per day than between 5 and 6 mg/kg per day and the lowest risk with dosing under 5 mg/kg per day.
Q: How does your study align with and/or expand upon previous research regarding HCQ risk?
A: An important prior study of hydroxychloroquine retinopathy was the 2014 study by Ronald B. Melles, MD, and Michael F. Marmor, MD, published in JAMA Ophthalmology. Prior to our present study, that was the largest study to use the modern screening method (optical coherence tomography) to detect HCQ retinopathy. That screening tool is more sensitive than older methods, so it can detect early/mild cases of retinopathy that are typically asymptomatic. Compared to older studies, that 2014 study found a much higher risk of HCQ retinopathy than was previously appreciated.
However, that 2014 study did have some key limitations that could affect the risk estimates, such as using prevalent cases. A key feature of our present study is that we took several important steps to generate more accurate risk estimates. This included using an incident user cohort and detecting incident retinopathy cases through serial review of optical coherence tomography (screening) studies.
To achieve a high degree of methodologic rigor in correctly identifying retinopathy outcomes, we had expert ophthalmologists perform masked adjudication of all screening studies, and we assessed the intra-rater reliability of these study interpretations. Therefore, our study adds to the literature more accurate estimates of retinopathy risk. We found a lower cumulative incidence of retinopathy than was identified in the 2014 study, but the risk is still noteworthy.
Also unique to our study, we graded the severity of HCQ retinopathy outcomes. This was important, as we found that the majority of retinopathy cases detected through routine screening are mild and presumed to be asymptomatic. This will likely be reassuring news for patients that we can screen for this adverse event to detect it early and prevent vision loss.
Another important difference was that we assessed the risk of retinopathy associated with using over 6 mg/kg per day, between 5 and 6 mg/kg per day, and less than 5 mg/kg per day, whereas the highest dosing group assessed in the 2014 study included all patients using over 5 mg/kg per day. The risk was considerably higher in the > 6 mg/kg per day group than in the 5-6 mg/kg per day group.
Q: How can rheumatologists and ophthalmologists use this new information specifically to better treat their patients?
A: Our study provides more accurate estimates of the risk of HCQ retinopathy than in prior studies. These risk estimates can be used when rheumatologists (and other clinicians who prescribe HCQ) consider the risks and benefits of this otherwise important and well-tolerated medication. The risk associated with different dose ranges could also inform dosing decisions, since dosing over 6 mg/kg per day may be more of a concern than using doses in the 5-6 mg/kg range. Ophthalmologists can also use these new risk estimates to counsel patients of the importance of HCQ retinopathy screening and can also hopefully provide some reassurance to patients that the risk of severe retinopathy is low as long as they are being monitored.

FROM ANNALS OF INTERNAL MEDICINE
A toddler presents with a dark line on a fingernail
Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.
Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.1,2
This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.3 In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.4 Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.1
What’s the differential diagnosis?
The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.
Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.
Treatment of subungual melanoma depends on disease stage and can range from wide local excision of the nail apparatus to amputation of the affected digit and management with a medical oncologist. Given the absence of concerning neoplastic findings or personal or family history of melanoma, subungual melanoma is unlikely in this patient.
Subungual hematoma is an accumulation of blood underneath the nail plate that is typically the result of acute or chronic trauma to the distal phalanx. It can present as purple, red, pink, brown, or black discoloration under the nail plate and is most commonly found on the first toe. With acute trauma, pain is usually present upon initial injury. Subungual hematomas typically resolve on their own with normal nail growth. The absence of a history of trauma or pain, and the linear appearance of the lesion in our patient are inconsistent with a subungual hematoma.
Onychomycosis is a fungal infection of the nail caused by dermatophytes, nondermatophytes, or yeasts. It may present with longitudinal melanonychia; however, it more often presents with other nail abnormalities such as nail thickening, yellow discoloration, onycholysis, splitting, subungual hyperkeratosis, and nail plate destruction, which are not present in this patient. Furthermore, onychomycosis is more common in adults than children. Diagnosis is usually made with potassium hydroxide (KOH) preparations, histopathologic examination of nail clippings with a periodic acid-Schiff stain, fungal culture, or PCR.
Glomus tumor is a rare, benign neoplasm originating from cells of the glomus body. It is often found in the subungual region, in addition to other areas rich in glomus bodies such as the fingertips, palms, wrists, and forearms. Subungual glomus tumors present as a red, purple, or blueish lesions under the nail plate. Distal notching or an overlying longitudinal fissure may be present. Subungual glomus tumors are typically associated with pinpoint tenderness, paroxysmal pain, and cold sensitivity, features that are not present in our patient. The history and examination of our patient are much more consistent with benign longitudinal melanonychia.
It appears that melanoma associated with longitudinal melanonychia is very rare in children. According to one review published in 2020, only 12 cases of pediatric subungual melanoma have been reported.5 Recent series have observed longitudinal melanonychia in large sets of children, with findings that demonstrate that the vast majority of longitudinal melanonychia either stops progressing or regresses. These investigations therefore recommend serial observation of longitudinal melanonychia except in rare circumstances.6,7
Given the lack of troubling findings or concerning history, our patient was managed with observation. On follow-up 6 months later, he was found to have no change in his nail pigmentation.

It may present with longitudinal melanonychia; however, it more often presents with other nail abnormalities such as nail thickening, yellow discoloration, onycholysis, splitting, subungual hyperkeratosis, and nail plate destruction, which are not present in this patient. Furthermore, onychomycosis is more common in adults than children. Diagnosis is usually made with potassium hydroxide (KOH) preparations, histopathologic examination of nail clippings with a periodic acid-Schiff stain, fungal culture, or PCR.
Glomus tumor is a rare, benign neoplasm originating from cells of the glomus body. It is often found in the subungual region, in addition to other areas rich in glomus bodies such as the fingertips, palms, wrists, and forearms. Subungual glomus tumors present as a red, purple, or blueish lesions under the nail plate. Distal notching or an overlying longitudinal fissure may be present. Subungual glomus tumors are typically associated with pinpoint tenderness, paroxysmal pain, and cold sensitivity, features that are not present in our patient. The history and examination of our patient are much more consistent with benign longitudinal melanonychia.
It appears that melanoma associated with longitudinal melanonychia is very rare in children. According to one review published in 2020, only 12 cases of pediatric subungual melanoma have been reported.5 Recent series have observed longitudinal melanonychia in large sets of children, with findings that demonstrate that the vast majority of longitudinal melanonychia either stops progressing or regresses. These investigations therefore recommend serial observation of longitudinal melanonychia except in rare circumstances.6,7
Given the lack of troubling findings or concerning history, our patient was managed with observation. On follow-up 6 months later, he was found to have no change in his nail pigmentation.

Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.
Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.1,2
This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.3 In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.4 Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.1
What’s the differential diagnosis?
The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.
Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.
Treatment of subungual melanoma depends on disease stage and can range from wide local excision of the nail apparatus to amputation of the affected digit and management with a medical oncologist. Given the absence of concerning neoplastic findings or personal or family history of melanoma, subungual melanoma is unlikely in this patient.
Subungual hematoma is an accumulation of blood underneath the nail plate that is typically the result of acute or chronic trauma to the distal phalanx. It can present as purple, red, pink, brown, or black discoloration under the nail plate and is most commonly found on the first toe. With acute trauma, pain is usually present upon initial injury. Subungual hematomas typically resolve on their own with normal nail growth. The absence of a history of trauma or pain, and the linear appearance of the lesion in our patient are inconsistent with a subungual hematoma.
Onychomycosis is a fungal infection of the nail caused by dermatophytes, nondermatophytes, or yeasts. It may present with longitudinal melanonychia; however, it more often presents with other nail abnormalities such as nail thickening, yellow discoloration, onycholysis, splitting, subungual hyperkeratosis, and nail plate destruction, which are not present in this patient. Furthermore, onychomycosis is more common in adults than children. Diagnosis is usually made with potassium hydroxide (KOH) preparations, histopathologic examination of nail clippings with a periodic acid-Schiff stain, fungal culture, or PCR.
Glomus tumor is a rare, benign neoplasm originating from cells of the glomus body. It is often found in the subungual region, in addition to other areas rich in glomus bodies such as the fingertips, palms, wrists, and forearms. Subungual glomus tumors present as a red, purple, or blueish lesions under the nail plate. Distal notching or an overlying longitudinal fissure may be present. Subungual glomus tumors are typically associated with pinpoint tenderness, paroxysmal pain, and cold sensitivity, features that are not present in our patient.

AD outcomes improved with lebrikizumab and topical steroids
, according to results of the 16-week phase 3 ADhere trial.
“Lebrikizumab, a monoclonal antibody inhibiting interleukin-13, combined with TCS was associated with reduced overall disease severity of moderate to severe AD in adolescents and adults, and had a safety profile consistent with previous lebrikizumab AD studies,” noted lead author Eric L. Simpson, MD, professor of dermatology at Oregon Health & Science University, Portland, and coauthors in their article on the study, which was published in JAMA Dermatology.
The double-blind trial, conducted at 54 sites across Germany, Poland, Canada, and the United States, included 211 patients, mean age 37.2 years, of whom 48.8% were female and roughly 22% were adolescents. Almost 15% were Asian, and about 13% were Black.
At baseline, participants had a score of 16 or higher on the Eczema Area and Severity Index (EASI), a score of 3 or higher on the Investigator’s Global Assessment (IGA) scale, AD covering a body surface area of 10% or greater, and a history of inadequate response to treatment with topical medications.
After a minimum 1-week washout period from topical and systemic therapy, participants were randomized in a 2:1 ratio to receive lebrikizumab plus TCS (n = 145) or placebo plus TCS (n = 66) for 16 weeks.
Lebrikizumab or placebo was administered by subcutaneous injection every 2 weeks; the loading and week-2 doses of lebrikizumab were 500 mg, followed by 250 mg thereafter. All patients were instructed to use low- to mid-potency TCS at their own discretion. Study sites provided a mid-potency TCS (triamcinolone acetonide 0.1% cream) and a low-potency TCS (hydrocortisone 1% cream), with topical calcineurin inhibitors permitted for sensitive skin areas.
Primary outcomes at 16 weeks included a 2-point or more reduction in IGA score from baseline and EASI-75 response. Patients in the lebrikizumab arm had superior responses on both of these outcomes, with statistical significance achieved as early as week 8 and week 4, respectively, and maintained through week 16. Specifically, 41.2% of those treated with lebrikizumab had an IGA reduction of 2 points or more, compared with 22.1% of those receiving placebo plus TCS (P = .01), and the proportion of patients achieving EASI-75 responses was 69.5% vs. 42.2%, respectively (P < .001).
Patients treated with lebrikizumab also showed statistically significant improvements, compared with TCS alone in all key secondary endpoints, “including skin clearance, improvement in itch, itch interference on sleep, and enhanced QoL [quality of life],” noted the authors. “This study captured the clinical benefit of lebrikizumab through the combined end point of physician-assessed clinical sign of skin clearance (EASI-75) and patient-reported outcome of improvement in itch (Pruritus NRS).”
The percentage of patients who achieved the combined endpoint was more than double for the lebrikizumab plus TCS group vs. the group on TCS alone, indicating that patients treated with lebrikizumab plus TCS “were more likely to experience improvement in skin symptoms and itch,” the investigators added.
The authors noted that most treatment-emergent adverse events “were nonserious, mild, or moderate in severity, and did not lead to study discontinuation.” These included conjunctivitis (4.8%), headache (4.8%), hypertension (2.8%), injection-site reactions (2.8%), and herpes infection (3.4%) – all of which occurred in 1.5% or less of patients in the placebo group.
“The higher incidence of conjunctivitis has also been reported in other biologics inhibiting IL [interleukin]–13 and/or IL-4 signaling, as well as lebrikizumab monotherapy studies,” they noted. The 4.8% rate of conjunctivitis reported in the combination study, they added, is “compared with 7.5% frequency in 16-week data from the lebrikizumab monotherapy studies. Although the mechanism remains unclear, it has been reported that conjunctival goblet cell scarcity due to IL-13 and IL-4 inhibition, and subsequent effects on the homeostasis of the conjunctival mucosal surface, results in ocular AEs [adverse events].”
“This truly is a time of great hope and promise for our patients with AD,” commented Zelma Chiesa Fuxench, MD, who was not involved in the study. “The advent of newer, targeted therapeutic agents for AD continues to revolutionize the treatment experience for our patients, offering the possibility of greater AD disease control with a favorable risk profile and less need for blood work monitoring compared to traditional systemic agents.”
On the basis of the study results, Dr. Chiesa Fuxench, of the department of dermatology at the University of Pennsylvania, Philadelphia, said in an interview that “lebrikizumab represents an additional option in the treatment armamentarium for providers who care for patients with AD.” She added that, “while head-to-head trials comparing lebrikizumab to dupilumab, the first FDA-approved biologic for AD, would be beneficial, to the best of my knowledge this data is currently lacking. However, based on the results of this study, we would expect lebrikizumab to work at least similarly to dupilumab, based on the reported improvements in IGA and EASI score.”
Additionally, lebrikizumab showed a favorable safety profile, “with most treatment-emergent adverse effects reported as nonserious and not leading to drug discontinuation,” she said. “Of interest to clinicians may be the reported rates of conjunctivitis in this study. Rates of conjunctivitis for lebrikizumab appear to be lower than those reported in the LIBERTY AD CHRONOS study for dupilumab – a finding that merits further scrutiny in my opinion, as this one of the most frequent treatment-emergent adverse events that I encounter in my clinical practice.”
The study was funded by Dermira, a subsidiary of Eli Lilly. Dr. Simpson reported personal fees and grants from multiple sources, including Dermira and Eli Lilly, the companies developing lebrikizumab. Several authors were employees of Eli Lilly. Dr. Fuxench disclosed serving as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, Pfizer, AbbVie, and Incyte, for which she has received honoraria for AD-related work. She is the recipient of research grants through Regeneron, Sanofi, Tioga, Vanda, Menlo Therapeutics, Leo Pharma, and Eli Lilly for work related to AD as well as honoraria for continuing medical education work related to AD sponsored through educational grants from Regeneron/Sanofi and Pfizer.

Manicure gone wrong leads to cancer diagnosis
. Now, she and her doctor are spreading the word about her ordeal as a lesson that speed and persistence in seeking treatment are the keys that make her type of cancer – squamous cell carcinoma – completely curable.
“She cut me, and the cut wasn’t just a regular cuticle cut. She cut me deep, and that was one of the first times that happened to me,” Grace Garcia, 50, told TODAY.com, recalling the November 2021 incident.
Ms. Garcia had been getting her nails done regularly for 20 years, she said, but happened to go to a different salon than her usual spot because she couldn’t get an appointment during the busy pre-Thanksgiving season. She doesn’t recall whether the technician opened packaging that signals unused tools.
She put antibiotic ointment on the cut, but it didn’t heal after a few days. Eventually, the skin closed and a darkened bump formed. It was painful. She went to her doctor, who said it was a “callus from writing,” she told TODAY.com. But it was on her ring finger, which didn’t seem connected to writing. Her doctor said to keep an eye on it.
Five months after the cut occurred, she mentioned it during a gynecology appointment and was referred to a dermatologist, who also advised keeping an eye on it. A wart developed. She went back to her primary care physician and then to another dermatologist. The spot was biopsied.
Squamous cell carcinoma is a common type of skin cancer, according to the American Academy of Dermatology. It can have many causes, but the cause in Ms. Garcia’s case was both very common and very rare: human papillomavirus, or HPV. HPV is a virus that infects millions of people every year, but it’s not a typical cause of skin cancer.
“It’s pretty rare for several reasons. Generally speaking, the strains that cause cancer from an HPV standpoint tend to be more sexually transmitted,” dermatologist Teo Soleymani told TODAY.com. “In Grace’s case, she had an injury, which became the portal of entry. So that thick skin that we have on our hands and feet that acts as a natural barrier against infections and things like that was no longer the case, and the virus was able to infect her skin.”
Dr. Soleymani said Ms. Garcia’s persistence to get answers likely saved her from losing a finger.
“Your outcomes are entirely dictated by how early you catch them, and very often they’re completely curable,” he said. “Her persistence – not only was she able to have a great outcome, she probably saved herself from having her finger amputated.”

Ms. Garcia had been getting her nails done regularly for 20 years, she said, but happened to go to a different salon than her usual spot because she couldn’t get an appointment during the busy pre-Thanksgiving season. She doesn’t recall whether the technician opened packaging that signals unused tools.
She put antibiotic ointment on the cut, but it didn’t heal after a few days. Eventually, the skin closed and a darkened bump formed. It was painful. She went to her doctor, who said it was a “callus from writing,” she told TODAY.com. But it was on her ring finger, which didn’t seem connected to writing. Her doctor said to keep an eye on it.
Five months after the cut occurred, she mentioned it during a gynecology appointment and was referred to a dermatologist, who also advised keeping an eye on it. A wart developed. She went back to her primary care physician and then to another dermatologist. The spot was biopsied.
Squamous cell carcinoma is a common type of skin cancer, according to the American Academy of Dermatology. It can have many causes, but the cause in Ms. Garcia’s case was both very common and very rare: human papillomavirus, or HPV. HPV is a virus that infects millions of people every year, but it’s not a typical cause of skin cancer.
“It’s pretty rare for several reasons. Generally speaking, the strains that cause cancer from an HPV standpoint tend to be more sexually transmitted,” dermatologist Teo Soleymani told TODAY.com. “In Grace’s case, she had an injury, which became the portal of entry. So that thick skin that we have on our hands and feet that acts as a natural barrier against infections and things like that was no longer the case, and the virus was able to infect her skin.”
Dr. Soleymani said Ms. Garcia’s persistence to get answers likely saved her from losing a finger.
“Your outcomes are entirely dictated by how early you catch them, and very often they’re completely curable,” he said. “Her persistence – not only was she able to have a great outcome, she probably saved herself from having her finger amputated.”
Scaly facial plaques
This patient was experiencing a flare of his psoriasis. Three factors contributed to the flare: noncompliance with his treatment regimen, decreased sunlight in the winter, and his lithium therapy. Though carcinogenic, certain wavelengths of UV light are beneficial for psoriasis, and the shorter days of winter can cause flaring of psoriasis (or relative flaring). In addition, lithium—the most effective therapy for this patient’s bipolar disorder—can worsen psoriasis.
Psoriasis is a chronic multisystem inflammatory disorder with characteristic skin findings that include well-demarcated micaceous plaques, nail pitting, and sometimes tendon pain and inflammatory arthritis. Severity can range from small, thin plaques that are intermittently noticeable on the elbows or knees to widespread ash-like plaques covering most of the body.
Good topical choices for facial skin include hydrocortisone 2.5% cream or desonide 0.05%. Nonsteroidal topical therapies that are safe for facial skin include tacrolimus 0.1% ointment or pimecrolimus 1% cream.1 These options may be used twice daily until the disease is controlled.
In many cases (as in this one), the patient’s previous psoriasis outbreaks could not be controlled with topical therapy alone. The patient had not responded to a previous methotrexate regimen, and more recently had been clear for several years on systemic ustekinumab, a monoclonal antibody. Dosed every 12 weeks, or sometimes every 8 weeks, ustekinumab is given by subcutaneous injection, usually in the abdomen, through normal skin. Ustekinumab was recently approved for home use with just 4 injections per year for maintenance therapy. However, the infrequency of the injections sometimes leads to noncompliance, as occurred with this patient. He had missed 2 doses since taking over his own dosing regimen.
Ultimately, the patient’s flare resolved when he was transitioned back to in-office treatment with ustekinumab.

AAD unveils updated guidelines for topical AD treatment in adults
, and topical phosphodiesterase-4 (PDE-4) and Janus kinase (JAK) inhibitors. The guidelines also conditionally recommend the use of bathing and wet wrap therapy but recommend against the use of topical antimicrobials, antiseptics, and antihistamines.
The development updates the AAD’s 2014 recommendations for managing AD with topical therapies, published almost 9 years ago. “At that time, the only U.S. FDA–approved systemic medication for atopic dermatitis was prednisone – universally felt amongst dermatologists to be the least appropriate systemic medication for this condition, at least chronically,” Robert Sidbury, MD, MPH, who cochaired a 14-member multidisciplinary work group that assembled the updated guidelines, told this news organization in an interview.
“Since 2017, there have been two different biologic medications approved for moderate to severe AD (dupilumab and tralokinumab) with certainly a third or more right around the corner. There have been two new oral agents approved for moderate to severe AD – upadacitinib and abrocitinib – with others on the way,” he noted. While these are not topical therapies, the purview of the newly released guidelines, he said, “there have also been new topical medications approved since that time (crisaborole and ruxolitinib). It was high time for an update.”
For the new guidelines, which were published online in the Journal of the American Academy of Dermatology, Dr. Sidbury, chief of the division of dermatology at Seattle Children’s Hospital, guidelines cochair Dawn M. R. Davis, MD, a dermatologist at Mayo Clinic, Rochester, Minn., and colleagues conducted a systematic review of evidence regarding the use of nonprescription topical agents such as moisturizers, bathing practices, and wet wraps, as well as topical pharmacologic modalities such as corticosteroids, calcineurin inhibitors, JAK inhibitors, PDE-4 inhibitors, antimicrobials, and antihistamines.
Next, the work group applied the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach for assessing the certainty of the evidence and formulating and grading clinical recommendations based on relevant randomized trials in the medical literature.
12 recommendations
Of the 12 recommendations made for adults with AD, the work group ranked 7 as “strong” based on the evidence reviewed, and the rest as “conditional.” The “strong” recommendations include the use of moisturizers; the use of tacrolimus 0.03% or 0.1%; the use of pimecrolimus 1% cream for mild to moderate AD; use of topical steroids; intermittent use of medium-potency topical corticosteroids as maintenance therapy to reduce flares and relapse; the use of the topical PDE-4 inhibitor crisaborole, and the use of the topical JAK inhibitor ruxolitinib.
Regarding ruxolitinib cream 1.5%, the work group advised that the treatment area “should not exceed 20% body surface area, and a maximum of 60 grams should be applied per week; these stipulations are aimed at reducing systemic absorption, as black box warnings include serious infections, mortality, malignancies (for example, lymphoma), major adverse cardiovascular events, and thrombosis.”
Conditional recommendations in the guidelines include those for bathing for treatment and maintenance and the use of wet dressings, and those against the use of topical antimicrobials, topical antihistamines, and topical antiseptics.
According to Dr. Sidbury, the topic of bathing generated robust discussion among the work group members. “Though [each group member] has strong opinions and individual practice styles, they were also able to recognize that the evidence is all that matters in a project like this, which led to a ‘conditional’ recommendation regarding bathing frequency backed by ‘low’ evidence,” he said. “While this may seem like ‘guidance’ that doesn’t ‘guide,’ I would argue it informs the guideline consumer exactly where we are in terms of this question and allows them to use their best judgment and experience as their true north here.”
In the realm of topical steroids, Dr. Sidbury said that topical steroid addiction (TSA) and topical steroid withdrawal (TSW) have been a “controversial but persistent concern” from some patients and providers. “Two systematic reviews of this topic were mentioned, and it was made clear that the evidence base [for the concepts] is weak,” he said. “With that important caveat ,the guideline committee delineated both a definition of TSW/TSA and potential risk factors.”
Dr. Sidbury marveled at the potential impact of newer medicines such as crisaborole and ruxolitinib on younger AD patients as well. Crisaborole is now Food and Drug Administration approved down to 3 months of age for mild to moderate AD. “This is extraordinary and expands treatment options for all providers at an age when parents and providers are most conservative in their practice,” he said. “Ruxolitinib, also nonsteroidal, is FDA approved for mild to moderate AD down to 12 years of age. Having spent a good percentage of my practice years either being able to offer only topical steroids, or later topical steroids and topical calcineurin inhibitors like tacrolimus or pimecrolimus, having additional options is wonderful.”
In the guidelines, the work group noted that “significant gaps remain” in current understanding of various topical AD therapies. “Studies are needed which examine quality of life and other patient-important outcomes, changes to the cutaneous microbiome, as well as long term follow-up, and use in special and diverse populations (e.g., pregnancy, lactation, immunosuppression, multiple comorbidities, skin of color, pediatric),” they wrote. “Furthermore, increased use of new systemic AD treatment options (dupilumab, tralokinumab, abrocitinib, upadacitinib) in patients with moderate to severe disease may result in a selection bias toward milder disease in current and future AD topical therapy studies.”
Use of topical therapies to manage AD in pediatric patients will be covered in a forthcoming AAD guideline. The first updated AD guideline, on comorbidities associated with AD in adults, was released in January 2022.
Dr. Sidbury reported that he serves as an advisory board member for Pfizer, a principal investigator for Regeneron, an investigator for Brickell Biotech and Galderma USA, and a consultant for Galderma Global and Microes. Other work group members reported having financial disclosures with many pharmaceutical companies.

A 50-year-old woman with no significant history presented with erythematous, annular plaques, and papules on the dorsal hands and arms
. The prevalence and incidence is approximately 0.1%-0.4%. Although the condition is benign, it may be associated with more serious conditions such as HIV and malignancy. GA affects women more frequently than men but can affect any age group, although it most commonly presents in those ages 30 years and younger. While the exact etiology is unknown, GA has been most strongly associated with diabetes mellitus, hyperlipidemia, and autoimmune diseases.
The disease presents as localized, annular erythematous plaques and papules on the dorsal hands and feet in approximately 75% of cases. However, eruptions may appear on the trunk and extremities and can be categorized into patchy, generalized, interstitial, subcutaneous, or perforating subtypes. The lesions are often asymptomatic and typically not associated with any other symptoms.
The pathogenesis of GA is still under investigation, but recent studies suggest that a Th1-mediated dysregulation of the JAK-STAT pathway may contribute to the disease. Other hypotheses include a delayed hypersensitivity reaction or cell mediated immune response. The mechanism may be multifaceted, and epidemiologic research suggests a genetic predisposition in White individuals, but these findings may be associated with socioeconomic factors and disparities in health care.
GA presents on histology with palisading histiocytes surrounding focal collagen necrobiosis with mucin deposition. Tissue samples also display leukocytic infiltration of the dermis featuring multinucleated giant cells. There are defining features of the different subtypes, but focal collagen necrosis, the presence of histiocytes, and mucin deposition are consistent findings across all presentations.
GA lesions commonly regress on their own, but they tend to recur and can be functionally and visually unappealing to patients. The most common treatments for GA include topical corticosteroids, intralesional corticosteroid injections, and other anti-inflammatory drugs. These interventions can be administered in a variety of ways as the inflammation caused by GA exists on a spectrum, and less severe cases can be managed with topical or intralesional treatment. Systemic therapy may be necessary for severe and recalcitrant cases. Other interventions that have shown promise in smaller studies include phototherapy, hydroxychloroquine, and TNF-alpha inhibitors.
This case and photo were submitted by Lucas Shapiro, BS, Nova Southeastern University College of Osteopathic Medicine, Tampa Bay Regional Campus, and Dr. Bilu Martin.

GA lesions commonly regress on their own, but they tend to recur and can be functionally and visually unappealing to patients. The most common treatments for GA include topical corticosteroids, intralesional corticosteroid injections, and other anti-inflammatory drugs. These interventions can be administered in a variety of ways as the inflammation caused by GA exists on a spectrum, and less severe cases can be managed with topical or intralesional treatment. Systemic therapy may be necessary for severe and recalcitrant cases. Other interventions that have shown promise in smaller studies include phototherapy, hydroxychloroquine, and TNF-alpha inhibitors.

Regular vitamin D supplements may lower melanoma risk
. They also found a trend for benefit with occasional use.
The study, published in Melanoma Research, involved almost 500 individuals attending a dermatology clinic who reported on their use of vitamin D supplements.
Regular users had a significant 55% reduction in the odds of having a past or present melanoma diagnosis, while occasional use was associated with a nonsignificant 46% reduction. The reduction was similar for all skin cancer types.
However, senior author Ilkka T. Harvima, MD, PhD, department of dermatology, University of Eastern Finland and Kuopio (Finland) University Hospital, warned there are limitations to the study.
Despite adjustment for several possible confounding factors, “it is still possible that some other, yet unidentified or untested, factors can still confound the present result,” he said.
Consequently, “the causal link between vitamin D and melanoma cannot be confirmed by the present results,” Dr. Harvima said in a statement.
Even if the link were to be proven, “the question about the optimal dose of oral vitamin D in order to for it to have beneficial effects remains to be answered,” he said.
“Until we know more, national intake recommendations should be followed.”
The incidence of cutaneous malignant melanoma and other skin cancers has been increasing steadily in Western populations, particularly in immunosuppressed individuals, the authors pointed out, and they attributed the rise to an increased exposure to ultraviolet radiation.
While ultraviolet radiation exposure is a well-known risk factor, “the other side of the coin is that public sun protection campaigns have led to alerts that insufficient sun exposure is a significant public health problem, resulting in insufficient vitamin D status.”
For their study, the team reviewed the records of 498 patients aged 21-79 years at a dermatology outpatient clinic who were deemed by an experienced dermatologist to be at risk of any type of skin cancer.
Among these patients, 295 individuals had a history of past or present cutaneous malignancy, with 100 diagnosed with melanoma, 213 with basal cell carcinoma, and 41 with squamous cell carcinoma. A further 70 subjects had cancer elsewhere, including breast, prostate, kidney, bladder, intestine, and blood cancers.
A subgroup of 96 patients were immunocompromised and were considered separately.
The 402 remaining patients were categorized, based on their self-reported use of oral vitamin D preparations, as nonusers (n = 99), occasional users (n = 126), and regular users (n = 177).
Regular use of vitamin D was associated with being more educated (P = .032), less frequent outdoor working (P = .003), lower tobacco pack years (P = .001), and more frequent solarium exposure (P = .002).
There was no significant association between vitamin D use and photoaging, actinic keratoses, nevi, basal or squamous cell carcinoma, body mass index, or self-estimated lifetime exposure to sunlight or sunburns.
However, there were significant associations between regular use of vitamin D and a lower incidence of melanoma and other cancer types.
There were significantly fewer individuals in the regular vitamin D use group with a past or present history of melanoma when compared with the nonuse group, at 18.1% vs. 32.3% (P = .021), or any type of skin cancer, at 62.1% vs. 74.7% (P = .027).
Multivariate logistic regression analysis revealed that regular vitamin D use was significantly associated with a reduced melanoma risk, at an odds ratio vs. nonuse of 0.447 (P = .016).
Occasional use was associated with a reduced, albeit nonsignificant, risk, with an odds ratio versus nonuse of 0.540 (P = .08).
For any type of skin cancers, regular vitamin D use was associated with an odds ratio vs. nonuse of 0.478 (P = .032), while that for occasional vitamin D use was 0.543 (P = .061).
“Somewhat similar” results were obtained when the investigators looked at the subgroup of immunocompromised individuals, although they note that “the number of subjects was low.”
The study was supported by the Cancer Center of Eastern Finland of the University of Eastern Finland, the Finnish Cancer Research Foundation, and the VTR-funding of Kuopio University Hospital. The authors report no relevant financial relationships.
