Aplasia cutis congenita is a rare condition characterized by the absence of skin layers. It is most common on the scalp, middle line, and it can be seen as a congenital ulcer involving periosteum, skull and dura. We present the case of a female newborn infant with a dysmorphic facies, a large scalp and skull defect exposing the dura. There was no cerebrospinal fluid leakage. The rarity of cases with large defects and small series reported make difficult to determinate the ideal treatment for aplasia cutis congenita. More studies are necessary to define the etiology and best management of this patients.
