A child with generalized hypertrichosis due to secondary topical minoxidil exposure.

Abstract

Hypertrichosis is defined as excessive hair growth anywhere on the body in either males or females. It may be caused by genetic conditions, endocrinological disorders, exposure to specific medications (including phenytoin, minoxidil and diazoxide) and other less frequent causes. We report the case of a 1-year-old boy with a family history of thyroid disease and alopecia areata who presented with generalized hypertrichosis due to secondary exposure to topical minoxidil. We discuss an uncommon cause of hypertrichosis and the importance of considering a wide differential diagnosis.
