A statistical tabulation was made of dermatoses seen in private practice in 3,860 consecutive Negro patients. The incidence of skin diseases in this group has been compared with that found in a recent study of an overwhelmingly Caucasian sample. Negro patients were found to have a higher incidence of atopic dermatitis and fungus infections, but less acne, fewer warts, and a much lower incidence of psoriasis, localized neurodermatitis, epithelioma, and keratoses. Therapeutic suggestions and comments have been made regarding vitiligo, hyperpigmentations, pseudofolliculitis of the beard, acne keloidalis, perifolliculitis capitis abscedens et suffodiens, and dermatosis papulosa nigra.
