Acne keloidalis in females: case report and review of literature.

Acne keloidalis, also known as folliculitis nuchae, is a form of chronic scarring folliculitis characterized by fibrotic papules and nodules of the nape of the neck and the occiput. It particularly affects men of African descent and is rarely ever seen in women. We here report the clinical findings of two Nigerian women who developed acne keloidalis. This report also reviews the pathogenesis of this disease.
