摘要：Aplasia cutis congenita (ACC) is a rare heterogenous disorder which is characterized by focal absence of skin since birth. Underlying structures such as bone or dura may also be involved. ACC has been considered to be a forme fruste of a neural tube defect by many authors. It might occur in isolation or in association with certain syndromes. We report a case of a new born male with membranous type of ACC over vertex extending to the left parietal region with partial agenesis of parietal bone and ectopic mongolian spot over left ankle.
