Aplasia cutis congenita corresponds to a heterogeneous group of disorders in which localized areas of the skin are absent or scarred at birth. Exogenic causes (amniotic adherence, intra uterine trauma or vascular abnormalities) have been accused but numerous familial cases with irregular autosomal dominant transmission have been reported. The majority of lesions are located on the scalp. The affected area is typically covered with a thin, transparent membrane. Rare significant underlying anomalies as meningomyeloceles or spinal dysraphism are associated. Surgical treatment produces good cosmetic results but deeper lesions require radiological evaluation of the underlying bone.
