Monilethrix: a rare hereditary condition

Monilethrix: A Report of Three Cases in Children Confirmed with Dermoscopy

Monilethrix is a rare hereditary disorder affecting hair resulting in hair fragility and alopecia. We report three patients of monilethrix who presented with complaints of sparse and brittle hair from early childhood. All three patients had multiple discrete hyperkeratotic papules over the scalp. Dermoscopy revealed beaded appearance of hair with the presence of elliptical nodes and intermittent constrictions on the hair shafts as well as broken hairs, which were confirmed with routine microscopic examination of hair. Dermoscopy helps in easier and faster diagnosis of monilethrix.

Monilethrix: a typical case report with microscopic and dermatoscopic findings

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.
