Aplasia Cutis Congenita: A Case Report.

Aplasia cutis congenita (ACC) is a rare developmental disorder that is not fully understood. It often occurs in isolation but can also be syndromic. Usually, there is an absence of the epidermis and dermis. It may be limited to the skin alone but may involve deeper structures. Research has identified a heterogeneous predisposition including genetic factors. Among patients with ACC, scalp involvement is common, however large scalp defects with the involvement of the skull is not common. We present a preterm neonate with a large scalp ACC with a wide skull defect.
