Acne keloidalis is characterized by infected keloid-like nodules in the short-cut nuchal region probably caused by recurving, ingrowing hairshafts. A case with a deep, partial-thickness burn of the hair-bearing part of the face of a man is reported. After healing, the patient started shaving himself thus inducing a severe state of acne keloidalis. It seems advisable in males not to shave during the first eight eight to ten months after a partial-thickness burn of the face in order to avoid this troublesome condition.
