Aplasia cutis congenita of the trunk with fetus papyraceus.

Aplasia cutis congenita (ACC) is the absence of localized or widespread areas of skin at birth. A frequently cited classification schema is based on location and the presence of associated anomalies. Histologically it is characterized by dermal fibrosis and absence of adenexal structures. We present a newborn female with extensive truncal ACC associated with fetus papyraceus.
