Abstract

Poliosis circumscripta describes a localized patch of white hair due to deficiency of melanin in the hair follicles. It is a feature of various conditions such as piebaldism, Vogt-Koyanagi-Harada syndrome, tuberous sclerosis, vitiligo, recent herpes zoster infection, or overlying a scalp neurofibroma. We report a rare case of poliosis circumscripta associated with halo nevus of the scalp. A 24-year-old woman presented with a 10 year history of an asymptomatic, pinkish nodule on the scalp which had overlying poliosis. On histopathological examination, dermal nevus cells were observed and the hair follicles of the depigmented patch were found to be devoid of pigment.
