A case of extensive aplasia cutis congenita: a conservative approach.

Aplasia cutis congenita is a rare, sporadic congenital malformation characterized by skin defects, sometimes extending to the underlying bone. We report a case of a boy born with a large rhomboid scalp and skull defect measuring 8 × 12 cm with no other anomalies. Conservative treatment led to the complete epithelization of the skin defect with secondary closure of the cranial vault without need for surgical intervention.
