Aplasia Cutis Congenita in a Baby born to Hyperthyroid Mother Treated with Methimazole During Pregnancy: A Case Report / 대한소아내분비학회지

ABSTRACT

Aplasia cutis congenita is a rare congenital anomaly characterized by focal absence of skin at birth. It most commonly manifests as a solitary defect on the scalp, but sometimes it may occur as multiple lesions. Frieden classified aplasia cutis congenita into nine types according to the associated anomalies, but a unifying theory has not been identified to explain the etiology of this disease. We report a case of a newborn with isolated aplasia cutis congenita on the scalp at birth, whose mother was treated with methimazole up to the 22 weeks of gestation due to hyperthyroidism.
