Generalized keratosis pilaris induced by testosterone injections in patient with CHARGE syndrome

Abstract

Keratosis pilaris (KP) is a common disorder of follicular keratinization characterized by keratotic follicular papules with varying degrees of perifollicular erythema. Keratosis pilaris affects up to half of normal children and up to three-quarters of children with atopic dermatitis. KP is prominent during teenage years, and least common in older people, but it may occur in children and adults of all ages. Here in this report, we describe a 13-year-old boy known to have CHARGE syndrome who developed generalized keratosis pilaris after injection of testosterone. To the best of our knowledge, this is the first reported case of Generalized keratosis pilaris induced by testosterone injection.
