Aplasia cutis congenita secondary to maternal exposureto carbimazole during pregnancy. A case report

ABSTRACT

Aplasia cutis congenita (ACC) is a rare anomaly presenting with absence of skin. It was first reported by Cordon in 1767. About 70% of cases manifests as a solitary defect on the scalp, but sometimes it may occur as multiple lesions. The lesions are typically well demarcated, non-inflamed, and they range in size from 0.5cm to 10cm. ACC may be circular, oval, linear, or stellate in configuration. At birth, lesions may appear as scars or ulcers1. They may appear as parchment-like scars with alopecia. Most lesions occur on the scalp vertex just lateral to the midline, but defects may also occur on the face, the trunk, or the limbs, sometimes symmetrically. The depth may involve only the epidermis and the upper dermis, resulting in minimal alopecic scarring, or the defect may extend to the deep dermis, the subcutaneous tissue, or rarely the periosteum, the skull, and the dura. ACC is most often a benign isolated defect, but it can be associated with other physical anomalies or malformation syndromes. Frieden classified them into 9 groups based on the number and presence or absence of other anomalies1. Nearly 86 percent belong to the first group with a solitary lesion. We report a case of Aplasia Cutis Congenita secondary to maternal exposure to carbimazole during pregnancy.
