Acne keloidalis of the scalp in a renal transplant patient treated with cyclosporine.

Sir, Acne keloidalis, also known as folliculitis cheloidalis, acne keloid, and dermatitis papillaris capillitii, is a dermatosis that occurs most commonly on the nape of the neck of young black males. It is characterized by the presence of small, smooth, firm papules, with occasional pustules. In a minority of cases, lesions are more numerous on the vertex or crown. Over time, the papules tend to coalesce into hairless keloid-like protuberant plaques (1). We describe here a Caucasian patient who developed acne keloidalis on the central portion of the scalp. The skin lesions appeared in this unusual location during treatment with cyclosporine.
