Monilethrix: a typical case report with microscopic and dermatoscopic findings

Elisa Fontenelle de Oliveira et al. An Bras Dermatol. 2015 Jan-Feb.

Abstract

Monilethrix is a rare hereditary condition generally considered to be an autosomal dominant disorder with variable penetrance. A case of a 6-year-old girl without a familial background for this disease is reported. The diagnosis was made by optic microscopy and dermoscopy. A therapeutic trial with topical minoxidil was conducted.
