Acne keloidalis in women.

Acne keloidalis is a chronic scarring folliculitis that most commonly occurs on the scalps of young black men. This disorder is described in two black women who had no evidence of androgen excess. Trauma to scalp hair may have precipitated the condition in one patient. Although it is uncommon, acne keloidalis should be considered a treatable cause of cicatricial alopecia in women.
