Mind the Gap atlas
How conditions actually present on Black skin.
Medical textbooks almost exclusively depict conditions on light skin. That omission has delayed real diagnoses, jaundice in newborns, meningitis rashes, Lyme bullseyes, Stevens-Johnson, Kawasaki, eczema, and many more present differently on Black skin. This atlas is the written clinical reference we wish had existed: we describe the presentation, tell you what to look for, and link out to open-access imagery from peer-reviewed and respected sources (we don't host clinical photographs here).
Body system
Acne and acne keloidalis nuchae on Black skin
Key cue: Dark marks after pimples often concern patients more than active acne. AKN (firm bumps on posterior scalp) is a distinct Black-skin entity needing dermatology care.
Read the atlas pageCentral centrifugal cicatricial alopecia (CCCA) on Black skin
Key cue: Slowly expanding hair loss from the crown outward, with smooth shiny scalp. Primarily affects Black women; early dermatology care preserves follicles.
Read the atlas pageEczema (atopic dermatitis) on Black skin
Key cue: Eczema on Black skin reads grey, violaceous, or darker-than-surrounding rather than red. Follicular-bump pattern and lichenification are common. The post-flare dark marks often worry families most.
Read the atlas pageHidradenitis suppurativa on Black skin
Key cue: Recurring painful deep bumps in armpits, groin, buttocks, or under breasts, not just 'boils' or 'acne'. Black women have 2-3× the severity and average 7-10 years to diagnosis.
Read the atlas pageMelasma on Black skin
Key cue: Symmetric dark-brown to slate-grey patches on forehead, cheeks, upper lip. Dermal pigment is less responsive to topical lighteners; daily SPF with iron oxide is the foundation.
Read the atlas pagePityriasis rosea on Black skin
Key cue: Single 'herald patch' followed in 1-2 weeks by many smaller oval lesions in a Christmas-tree distribution on the trunk. On Black skin, lesions are hyperpigmented or violaceous rather than pink-salmon.
Read the atlas pagePsoriasis on Black skin
Key cue: Plaques appear violaceous or hyperpigmented with thicker silvery-grey scale. 'Salmon pink' descriptions miss Black-skin psoriasis, use the sharp border + scale + distribution instead.
Read the atlas pageRosacea on Black skin
Key cue: Rosacea is under-diagnosed in Black patients by up to 75%. Look for burning/stinging, centrofacial papules/pustules, and flushing that reads as darkening rather than red.
Read the atlas pageSeborrheic dermatitis on Black skin
Key cue: Ring-shaped (annular/petaloid) hypopigmented patches with fine scale on the face are a Black-skin variant distinct from the flaky-scalp textbook picture.
Read the atlas pageTinea versicolor (pityriasis versicolor) on Black skin
Key cue: Oval hypo- (sometimes hyper-) pigmented patches with fine scale on upper trunk, shoulders, neck. KOH prep ('spaghetti and meatballs') confirms and rules out vitiligo.
Read the atlas pageVitiligo on Black skin
Key cue: Chalk-white patches with sharp borders, usually symmetric. Contrast against Black skin is high; psychosocial impact is significant. Treatment works, early dermatology referral matters.
