Abstract

A 13-year-old girl presented with a history of red scaly plaques involving the chest, arms and legs beginning in infancy. Punch biopsy revealed psoriasiform hyperplasia and pallor of the epidermis. The patient s serum zinc level was 36 mug/dl [nl. 66-144 mug/dl]. A diagnosis of acrodermatitis enteropathica was established and the patient responded well to zinc replacement therapy. Acrodermatitis enteropathica is a rare autosomal recessive disorder caused by mutations in SLC39A4, which encodes the tissue-specific zinc transporter ZIP4.
