THE ADOLESCENT boy pictured in the figures has had lesions in this area since birth. The vesicles, limited to the left shoulder and axilla, have enlarged and have become more numerous throughout these years. They are slightly pruritic. During the past 2 years, several of the vesicles have intermittently become hemorrhagic and have discharged clear fluid. The patient has been in excellent health.
