Synopsis

Acrodermatitis enteropathica is a rare autosomal recessive disease caused by abnormal zinc absorption due to a transport deficiency across the small intestine. The disease typically presents when the child is weaned from breast milk to cow's milk, or after 4–10 weeks in exclusively formula-fed infants. The characteristic skin eruption is typically the first clinical sign of disease. The affected infant may also exhibit failure to thrive, apathy, irritability, photophobia, diarrhea, and alopecia.

Identical clinical findings may result from acquired zinc deficiency due to other causes. It may be seen in premature infants who are exclusively breast fed in the setting of increased metabolic demands and declining levels of zinc in the mother's breast milk. Zinc deficiency has rarely been linked to a defect in the transfer of zinc into breast milk. Historically, it was seen in infants receiving parenteral nutrition, although zinc supplementation has now become routine. Clinicians should be aware of the possibility that hereditary acrodermatitis enteropathica can be mimicked in infants receiving parenteral nutrition formulations because of a disease such as biliary atresia.

For more information, see OMIM.
