Monilethrix with Variable Expressivity
A 32-year-old male presented with decreased hair over the scalp and body since childhood. Patient was asymptomatic, and there was no history suggestive of impaired psychomotor development. He did not give any history of similar illness in his family members. Examination showed diffuse hair loss with short and brittle hairs over scalp, predominantly over the occipital region []. The moustache and pubic area also showed short broken hairs. Beard, axillary and body hairs were absent []. Follicular keratotic papules were seen over the occiput, nape of neck and extensor arms []. The eyes, nails and teeth were normal. Light microscopy of hair showed beaded appearance with elliptical nodes separated by narrower internodes thus establishing the diagnosis of monilethrix [].
