Alopecia areata in infants and newborns

Abstract

Alopecia areata is a common cause of nonscarring hair loss in children and adults. In newborns and very young infants, however, it is thought to be extremely rare. In this article we describe five cases of alopecia areata in patients less than 6 months of age and briefly discuss the pertinent differential diagnosis of infants and newborns with both patchy and complete hair loss. We propose that alopecia areata may be more common in this age group than the literature suggests.
