title: Acrodermatitis enteropathica.
abstract: A case of acrodermatitis enteropathica belatedly recognized in a pregnant 23-year-old woman is reported. The condition was not specifically diagnosed during childhood. It cleared at puberty but recurred during two of three pregnancies in the form of pustular, vesiculobullous, and psoriasiform lesions. There were no associated signs or symptoms in other organs. Initial diagnoses upon the recurrence during the third pregnancy were herpes gestationis and impetigo herpetiformis. A markedly decreased serum zinc level (18 micrograms/dl) was found. Treatment with zinc sulfate was instituted, and within 3 days the cutaneous lesions began to clear. Two months after the birth of a healthy child, and without further therapy, all lesions had resolved and the serum zinc level was nearly normal. Acrodermatitis enteropathica should be considered in the differential diagnosis of unresponsive bullous dermatoses occurring during pregnancy.
