[Aplasia cutis congenita is a rare and possibly overlooked congenital anomaly].

Aplasia cutis congenita (ACC) is a rare congenital defect of the skin. In this study we present the diagnosis and management of the condition. In 1997-2009 a total of 65 ACC cases were registered in the Danish National Patient Registry (1:13.000 births). The mortality among these cases was 1.6% (one case) though the death was not attributable to ACC, which is far lower than described in international studies.
