Sarcoidosis is a granulomatous disease that may affect the skin in addition to multiple body organ systems, including the lungs. Bilateral hilar adenopathy on a chest radiograph is the most common finding. Sarcoidosis also has a variety of cutaneous manifestations. Early diagnosis is vital, as patients with with sarcoidosis and pulmonary fibrosis have a shortened life span compared to the overall population.¹ With a growing skin of color population, it is important to recognize sarcoidosis as soon as possible.²

Epidemiology

People of African descent have the highest sarcoidosis prevalence in the United States.³ In the United States, the incidence of sarcoidosis in Black individuals peaks in the fourth decade of life. A 5-year study in a US health maintenance organization found that the age-adjusted annual incidence was 10.9 per 100,000 cases among Whites and 35.5 per 100,000 cases among Blacks.⁴

Key clinical features in people with darker skin tones:

• Papules are seen in sarcoidosis, primarily on the face, and may start as orange hued or yellow-brown and then become brown-red or pink to violaceous before involuting into faint macules.^5-7

• When round or oval sarcoid plaques appear, they often are more erythematous. In skin of color, plaques may become hypopigmented.⁸

• Erythema nodosum, the most common nonspecific cutaneous lesion seen in sarcoidosis, is less commonly seen in those of African and Asian descent.^9-11 This is in contrast to distinctive forms of specific sarcoid skin lesions such as lupus pernio and scar sarcoidosis, as well as papules and plaques and minor forms of specific sarcoid skin lesions including subcutaneous nodules; hypopigmented macules; psoriasiform lesions; and ulcerative, localized erythrodermic, ichthyosiform, scalp, and nail lesions.

• Lupus pernio is a cutaneous manifestation of sarcoidosis that appears on the face. It looks similar to lupus erythematosus and occurs most commonly in women of African descent.^8,12

• Hypopigmented lesions are more common in those with darker skin tones.⁹

• Ulcerative lesions are more common in those of African descent and women.¹³

• Scalp sarcoidosis is more common in patients of African descent.¹⁴

• Sarcoidosis may develop at sites of trauma, such as scars and tattoos.^15-17

Worth noting

The cutaneous lesions seen in sarcoidosis may be emotionally devastating and disfiguring. Due to the variety of clinical manifestations, sarcoidosis may be misdiagnosed, leading to delays in treatment.¹⁸

Health disparity highlight

Patients older than 40 years presenting with sarcoidosis and those of African descent have a worse prognosis.¹⁹ Despite adjusting for race, ethnic group, age, and sex, patients with low income and financial barriers present with more severe sarcoidosis.²⁰

C Seborrheic dermatitis in a man with erythema, faint scale, and postinflammatory hypopigmentation that are especially prominent in the nasolabial folds.

D Seborrheic dermatitis in a man with erythema and scale of the eyebrows and glabellar region.

Seborrheic dermatitis (SD) is an inflammatory condition that is thought to be part of a response to Malassezia yeast. The scalp and face are most commonly affected, particularly the nasolabial folds, eyebrows, ears, postauricular areas, and beard area. Men also may have SD on the mid upper chest in association with chest hair. In infants, the scalp and body skin folds often are affected.

Epidemiology

SD affects patients of all ages: infants, adolescents, and adults. It is among the most common dermatologic diagnoses reported in Black patients in the United States.¹

Key clinical features in darker skin tones

• In those with darker skin tones, arcuate, polycyclic, or petaloid (flower petallike) plaques may be present (FIGURE A). Also, hypopigmented patches and plaques may be prominent (FIGURES B AND C). The classic description includes thin pink patches and plaques with white greasy scale on the face (FIGURE D).
• The scalp may have diffuse scale or isolated scaly plaques.

Worth noting

• In those with tightly coiled hair, there is a predisposition for dry hair and increased risk for breakage.
• Treatment plans for patients with SD often include frequent hair washing. However, in those with tightly coiled hair, the treatment plan may need to be modified due to hair texture, tendency for dryness, and washing frequency preferences. Washing the scalp at least every 1 to 2 weeks may be a preferred approach for those with tightly coiled hair at increased risk for dryness/breakage vs washing daily.² In a sample of 201 caregivers of Black girls, Rucker Wright et al3 found that washing the hair more than once per week was not correlated with a lower prevalence of SD.
• If tightly coiled hair is temporarily straightened with heat (eg, blow-dryer, flat iron), adding a liquid-based treatment such as clobetasol solution or fluocinonide solution will cause the hair to revert to its normal curl pattern.
• It is appropriate to ask patients for their vehicle preference for medications.² For example, if clobetasol is the treatment selected for the patient, the vehicle can reflect patient preference for a liquid, foam, cream, or ointment.
• Some antifungal/antiyeast shampoos may cause further hair dryness and breakage.
• Treatment may be delayed because patients often use various topical pomades and ointments to cover up the scale and help with pruritus.
• Diffuse scale of tinea capitis in school- aged children can be mistaken for SD, which leads to delayed diagnosis and treatment.
• Clinicians should become comfortable with scalp examinations in patients with tightly coiled hair. Patients with chief concerns related to their hair and scalp expect their clinicians to touch these areas. Avoid leaning in to examine the patient without touching the patient’s hair and scalp.^2,4

Health disparity highlight

SD is among the most common cutaneous disorders diagnosed in patients with skin of color.^1,5 Delay in recognition of SD in those with darker skin tones leads to delayed treatment. SD of the face can cause notable postinflammatory pigmentation alteration. Pigmentation changes in the skin further impact quality of life.

A 30-year-old man presented to the clinic with a complaint of small painful lumps in his armpit. He stated that he initially experienced some itching and discomfort, but after a while he noticed some red, tender, swollen areas. He also mentioned an odorous yellow fluid that would sometimes drain from the lumps. Since first noticing them 2 years earlier, he reported that the nodules had disappeared and reappeared on their own several times.

On physical exam, several small red subcutaneous nodules were present in the axilla and tender to palpation (FIGURE 1A). The patient also had comedonal acne on his back (FIGURE 1B). The patient’s body mass index was 31, and he was a nonsmoker.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

 

 

Diagnosis: Hidradenitis suppurativa

The characteristic location and morphology of the lesions, along with the chronicity and odor, were critical in arriving at a diagnosis of hidradenitis suppurativa (HS).

HS is a chronic, inflammatory skin condition that normally manifests in areas of apocrine sweat glands, including the axilla, groin, and perianal, perineal, and inframammary locations.¹ It begins when an abnormal hair follicle gets occluded and ruptures, spilling keratin and bacteria into the dermis. An inflammatory response can ensue with surrounding neutrophils and lymphocytes, which leads to abscess formation and destruction of the pilosebaceous unit. Sinus tracts form between the lesions, and a cycle of scarring, fistulas, and contractures can occur.

In this case, the comedones from acne conglobata on the patient’s back indicated a more global follicular occlusion disorder. The characteristic triad is hidradenitis suppurativa, acne conglobata, and dissecting cellulitis of the scalp—of which the patient had 2.

Even when surgical excisions are performed, medical treatment is needed to prevent new lesions and recurrences.

Other potential causes of the pathology include abnormal secretion of apocrine glands, abnormal antimicrobial peptides, deficient numbers of sebaceous glands, and abnormal invaginations of the epidermis.² Increased levels of tumor necrosis factor alpha and other cytokines have been detected in HS lesions and are a potential target for therapy.

The prevalence of HS in the United States is approximately 0.1%.³ The condition typically begins between the ages of 18 and 39 years. The ratio of women to men affected by the condition is 3:1.² There is no evident racial or ethnic predilection. There is an association with diabetes and Crohn disease.³ Obesity and smoking are risk factors.¹

The differential includes an array of common skin conditions

The differential diagnosis in this case included carbuncles, cysts, acne, and abscesses.

A furuncle or carbuncle can result from an infection of hair follicles that can manifest as individual (furuncle) or clusters of (carbuncle) red, painful boils. They form on parts of the skin where hair grows, including the face, neck, armpits, shoulders, and buttocks. They respond well to treatment with antibiotics and incision and drainage. They can be recurrent but usually don’t cluster together in apocrine-rich areas, as seen with HS.

Epidermal inclusion cysts are keratin-filled inclusion cysts with epithelial-lined cyst walls. The cysts are subcutaneous and occasionally more superficial. They can occur almost anywhere but are most often found on the back, scalp, neck, face, and chest. They are usually solitary; however, when there are multiple cysts, they are not linked by sinus tracts as found in HS.

Inflammatory acne lesions tend to form on the face, neck, back, chest, and shoulders, while HS lesions appear most often in apocrine-rich intertriginous areas.

Skin abscesses are local deep infections of the skin caused by bacterial pathogens. The most common agent is Staphylococcus aureus (frequently methicillin resistant). Injection drug use and immunosuppression are risk factors. Although bacteria do not cause HS lesions, bacteria can exacerbate HS through colonization.

No lab test needed to diagnose hidradenitis suppurativa

Diagnosis of HS is largely clinical and based on a patient’s history and physical exam findings.² No specific laboratory test is needed.

Although the patient in this case did have comedonal acne on his back, the lesions that prompted his visit were in an apocrine-rich area, were recurrent, and broke open on their own to release foul-smelling contents—all typical characteristics of HS.

Treatment depends on the severity of the condition

There are 3 stages of HS: Hurley stage I involves abscess formation without tracts or scars. Hurley stage II involves recurrent abscesses with sinus tracts and scarring. Hurley stage III has diffuse involvement with multiple interconnected sinus tracts and abscesses across an entire area.² Our patient fits into Hurley stage III.

Evidence-based treatment of mild disease (Hurley stage I) includes topical clindamycin 1% solution/gel bid or doxycycline 100 mg bid for widespread disease (Hurley stage II or resistant stage I).² Chlorhexidine and benzoyl peroxide washes are also often recommended.³ If a patient does not respond to this treatment or the condition is moderate to severe, then clindamycin 300 po bid (with or without rifampin 600/d po) for 10 weeks should be considered.^4,5 In a randomized placebo-controlled trial that compared the efficacy of oral clindamycin vs clindamycin plus rifampin in patients with HS, both therapeutic options were statistically equivalent.⁵ One small, randomized controlled study of patients with mild-to-moderate HS showed that tetracycline 500 mg bid for 3 months resulted in fewer abscesses and nodules but was not superior to topical clindamycin.³

If the patient doesn’t show improvement (Hurley stage III), then adalimumab is an option, as follows: 160 mg subcutaneously at Week 0, 80 mg at Week 2, and then 40 mg weekly, if needed.⁴ Adalimumab is currently the only FDA-approved treatment for HS. Infliximab by IV infusion can be effective in improving pain, disease severity, and quality of life in patients with moderate-to-severe HS.³ This patient was also a candidate for treatment with systemic retinoids (isotretinoin or acitretin), which could have helped both the HS and the acne conglobata.

Continue to: Intralesional steroid injectiosn with triamcinolone

Intralesional steroid injections with triamcinolone 10 mg/mL can reduce local pain and inflammation rapidly. Pain management is also critical, as HS is painful. First-line therapy includes nonsteroidal anti-inflammatory drugs, acetaminophen, atypical anticonvulsants, and serotonin and norepinephrine reuptake inhibitors.² Opiate analgesics may be needed for breakthrough pain in patients with severe disease. Avoiding tight clothing, harsh products, and adhesive dressings, as well as using clear petroleum jelly, can prevent skin trauma and help with healing. Weight loss and smoking cessation are also associated with better outcomes.^6,7

If medical management fails …

If there is no improvement with medical management, it may be time to consider local procedures such as unroofing/deroofing, punch debridement, skin-tissue-sparing excision with electrosurgical peeling, and laser excision. Incision and drainage may be necessary for acutely inflamed, painful abscesses but should not be routinely performed because lesions can recur.³

Referral to a plastic surgeon is necessary when patients are considering wide excisions of largely affected areas. Even when surgical excisions are performed, medical treatment is needed to prevent new lesions and recurrences.

Our patient was treated initially with oral doxycycline 100 mg bid and intralesional triamcinolone (10 mg/mL) in the most tender lesions. He was also provided with a prescription for ibuprofen 800 mg tid to be taken with meals. The family physician encouraged the patient to lose weight. The patient derived some benefit from treatment but continued to experience new painful lesions.

Hidradenitis suppurativa is painful, and thus, pain management is critical.

The physician prescribed oral clindamycin 300 mg bid at a follow-up visit to replace the oral doxycycline. When this failed, the patient was sent for labs to determine if he would be a candidate for adalimumab. When the screening labs were normal, a prescription for adalimumab was provided: 160 mg subcutaneously at Week 0, 80 mg at Week 2, and then 40 mg weekly.⁴

A 30-year-old man presented to the clinic with a complaint of small painful lumps in his armpit. He stated that he initially experienced some itching and discomfort, but after a while he noticed some red, tender, swollen areas. He also mentioned an odorous yellow fluid that would sometimes drain from the lumps. Since first noticing them 2 years earlier, he reported that the nodules had disappeared and reappeared on their own several times.

On physical exam, several small red subcutaneous nodules were present in the axilla and tender to palpation (FIGURE 1A). The patient also had comedonal acne on his back (FIGURE 1B). The patient’s body mass index was 31, and he was a nonsmoker.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

 

 

Diagnosis: Hidradenitis suppurativa

The characteristic location and morphology of the lesions, along with the chronicity and odor, were critical in arriving at a diagnosis of hidradenitis suppurativa (HS).

HS is a chronic, inflammatory skin condition that normally manifests in areas of apocrine sweat glands, including the axilla, groin, and perianal, perineal, and inframammary locations.¹ It begins when an abnormal hair follicle gets occluded and ruptures, spilling keratin and bacteria into the dermis. An inflammatory response can ensue with surrounding neutrophils and lymphocytes, which leads to abscess formation and destruction of the pilosebaceous unit. Sinus tracts form between the lesions, and a cycle of scarring, fistulas, and contractures can occur.

In this case, the comedones from acne conglobata on the patient’s back indicated a more global follicular occlusion disorder. The characteristic triad is hidradenitis suppurativa, acne conglobata, and dissecting cellulitis of the scalp—of which the patient had 2.

Even when surgical excisions are performed, medical treatment is needed to prevent new lesions and recurrences.

Other potential causes of the pathology include abnormal secretion of apocrine glands, abnormal antimicrobial peptides, deficient numbers of sebaceous glands, and abnormal invaginations of the epidermis.² Increased levels of tumor necrosis factor alpha and other cytokines have been detected in HS lesions and are a potential target for therapy.

The prevalence of HS in the United States is approximately 0.1%.³ The condition typically begins between the ages of 18 and 39 years. The ratio of women to men affected by the condition is 3:1.² There is no evident racial or ethnic predilection. There is an association with diabetes and Crohn disease.³ Obesity and smoking are risk factors.¹

The differential includes an array of common skin conditions

The differential diagnosis in this case included carbuncles, cysts, acne, and abscesses.

A furuncle or carbuncle can result from an infection of hair follicles that can manifest as individual (furuncle) or clusters of (carbuncle) red, painful boils. They form on parts of the skin where hair grows, including the face, neck, armpits, shoulders, and buttocks. They respond well to treatment with antibiotics and incision and drainage. They can be recurrent but usually don’t cluster together in apocrine-rich areas, as seen with HS.

Epidermal inclusion cysts are keratin-filled inclusion cysts with epithelial-lined cyst walls. The cysts are subcutaneous and occasionally more superficial. They can occur almost anywhere but are most often found on the back, scalp, neck, face, and chest. They are usually solitary; however, when there are multiple cysts, they are not linked by sinus tracts as found in HS.

Inflammatory acne lesions tend to form on the face, neck, back, chest, and shoulders, while HS lesions appear most often in apocrine-rich intertriginous areas.

Skin abscesses are local deep infections of the skin caused by bacterial pathogens. The most common agent is Staphylococcus aureus (frequently methicillin resistant). Injection drug use and immunosuppression are risk factors. Although bacteria do not cause HS lesions, bacteria can exacerbate HS through colonization.

B A teenaged Black boy with acne papules and pustules on the face. There are comedones, hyperpigmented macules, and pustules on the cheek.

C A teenaged Black girl with pomade acne. The patient used various hair care products, which obstructed the pilosebaceous units on the forehead.

Epidemiology

Acne is a leading dermatologic condition in individuals with skin of color in the United States.¹

Key clinical features in people with darker skin tones include:

• erythematous or hyperpigmented papules or comedones
• hyperpigmented macules and postinflammatory hyperpigmentation (PIH)
• increased risk for keloidal scars.²

Worth noting

• Patients with darker skin tones may be more concerned with the dark marks (also referred to as scars or manchas in Spanish) than the acne itself. This PIH may be viewed by patients as the major problem.
• Acne medications such as azelaic acid and some retinoids (when applied appropriately) can treat both acne and PIH.³
• Irritation from topical acne medications, including retinoid dermatitis, may lead to more PIH. Using noncomedogenic moisturizers and applying medication appropriately (ie, a pea-sized amount of topical retinoid per application) may help limit irritation.^4,5
• One type of acne seen more commonly, although not exclusively, in Black patients is pomade acne, which principally appears on the forehead and is associated with use of hair care and styling products (FIGURE C).

Health disparity highlight

Disparities in access to health care exist for those with dermatologic concerns. According to one study, African American (28.5%) and Hispanic patients (23.9%) were less likely to be seen by a dermatologist solely for the diagnosis of a dermatologic condition compared to Asian and Pacific Islander patients (36.7%) or White patients (43.2%).¹ Noting that isotretinoin is the most potent systemic therapy for severe cystic acne vulgaris, Bell et al⁶ reported that Black patients had lower odds of receiving isotretinoin compared to White patients. Hispanic patients had lower odds of receiving a topical retinoid, tretinoin, than non-Hispanic patients.⁶

B Elbow and forearm with violaceous, well-demarcated plaques with micaceous scale and hyperpigmented patches around the active plaques in a 58-year-old Black man.

Epidemiology

Psoriasis prevalence in the United States has been estimated at 3.7%.^1-3 If broken down by race or ethnicity, the prevalence of psoriasis varies: 2.5% to 3.7% in White adults^1-4; 1.3% to 2% in Black adults^1-4; 1.6% in Hispanics/other adults^1-3; 1% in children overall; 0.29% in White children^1,5; and 0.06% in Black children.^1,5

Key clinical features in people with darker skin tones include:

• plaques that may appear more violaceous in color instead of pink or erythematous
• higher body surface area of involvement⁴ and thicker, more scaly plaques⁶
• increased likelihood of postinflammatory hyperpigmentation (PIH).

Worth noting

Although individuals of all skin tones may experience the psychosocial impact of psoriasis, quality-of-life measures have been found to be worse in those with skin of color (SOC) compared to White patients. ^1,4 This may be due to the lingering PIH and hypopigmentation that occurs even after inflammatory plaques are treated. Of course, lack of access to care contributes to greater disease burden and more devastating psychological impact.

Health disparity highlight

Psoriasis may be underreported and underdiagnosed in individuals with SOC, as factors contributing to health care disparities may play a role, such as access to health care in general,^1,7 and access to clinicians proficient in diagnosing cutaneous diseases in SOC may be delayed.⁸

Biologic medications are used less often in Black patients than in White patients, despite biologic medications being very efficacious for treatment of psoriasis.^1,9,10

THE COMPARISON

A Pink scaling plaques and erythematous erosions in the antecubital fossae of a 6-year-old White boy.

B Violaceous, hyperpigmented, nummular plaques on the back and extensor surface of the right arm of a 16-month-old Black girl.

C Atopic dermatitis and follicular prominence/accentuation on the neck of a young Black girl.

Epidemiology

People of African descent have the highest atopic dermatitis prevalence and severity.

Key clinical features in people with darker skin tones include:

• follicular prominence
• papular morphology
• prurigo nodules
• hyperpigmented, violaceous-brown or gray plaques instead of erythematous plaques
• lichenification
• treatment resistant.^1,2

Worth noting

Postinflammatory hyperpigmentation and postinflammatory hypopigmentation may be more distressing to the patient/family than the atopic dermatitis itself.

Health disparity highlight

In the United States, patients with skin of color are more likely to be hospitalized with severe atopic dermatitis, have more substantial out-of-pocket costs, be underinsured, and have an increased number of missed days of work. Limited access to outpatient health care plays a role in exacerbating this health disparity.^3,4
