[Aplasia cutis congenita]

Communication of fifteen cases of Aplasia Cutis Congenita, seen from 1971 to 1977, in the Department of Pediatric Dermatology at the Hospital del Niño DIF (formerly IMAN). Patients of both sexes were equally affected. The scalp was by far the most common location of lesions. Lesiones were usually single and when multiple, they were symmetrical. The family history for the disease was negative. No relationship could be found with obstetric trauma or with the number of pregnancies. Epithelialized lesions were present in fourteen cases and ulcerated lesions in one. The more frequent congenital associated malformations were: cutaneous, neurological, ocular and osseous.
