This module examines common inflammatory skin conditions - including acne, atopic eczema, seborrheic dermatitis, psoriasis, lichen planus, pityriasis rosea, and rosacea - and how their epidemiology, presentation, and treatment can differ in patients with darker skin tones.

This module covers disorders of pigmentation - including vitiligo, albinism, melasma, pityriasis alba, and post-inflammatory hyperpigmentation - along with keloid scarring and the dermatologic effects of skin-bleaching practices, with attention to how these conditions present in darker skin tones.

This module covers common bacterial skin infections in patients with darker skin tones, ranging from superficial pyogenic infections such as impetigo, folliculitis, and furuncles to deeper and toxin-mediated infections like staphylococcal scalded skin syndrome, erysipelas, and cellulitis, as well as syphilis and cutaneous tuberculosis.

This module examines viral skin infections in patients with darker skin tones, including herpes simplex virus, varicella zoster virus (chickenpox and shingles), human papillomavirus-related warts, and molluscum contagiosum.

This module covers fungal skin infections in patients with darker skin tones, focusing on dermatophyte (tinea) infections of the skin, hair, and nails, including tinea faciei, tinea corporis, tinea capitis, tinea barbae, and onychomycosis.

This module covers common parasitic skin infestations in patients with darker skin tones, including scabies, pediculosis (head, body, and pubic lice), and cutaneous larva migrans.

This module examines how HIV-related immunosuppression alters the presentation and severity of skin disease, covering infectious skin conditions (viral, bacterial, fungal, and parasitic), inflammatory dermatoses, drug eruptions, and HIV-associated neoplasms, with attention to the relationship between CD4 count and disease severity.

This module covers hair and scalp disorders common in patients with darker skin tones, including hair biology and classification of alopecia, non-scarring conditions such as alopecia areata, telogen effluvium, and traction alopecia, and scarring alopecias such as central centrifugal cicatricial alopecia and frontal fibrosing alopecia.

This module covers cutaneous drug reactions in patients with darker skin tones, from the underlying hypersensitivity mechanisms through common presentations such as fixed and morbilliform drug eruptions and urticaria/angioedema, to severe, life-threatening reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis.

This module covers cutaneous and systemic connective tissue diseases in patients with darker skin tones, including cutaneous and systemic lupus erythematosus, systemic sclerosis/scleroderma, and dermatomyositis.
