Abstract:
Hypertrichosis is an overgrowth of hair not localized to the anclro en dependent areas of the skin. It may be congenital or acquired, localized or generalized localized hypertrichosis may occur in some types of pigrnentary nevi, chronic inflammation or irration, topical application of androgen or steroid, & localized myxedema. We report herein three i:ases of unilateral localized hypertrichosis with or without a brownish hyperpigmented patch developing on the face of a male adol scent. There are no known cau:,es of localized hyper trichosis. Histopath logically, it is characterized by increased melaniii pigment in the basal layer of the epidermis & enlarged hair follicles containing coarser liair. Electron microscopic findings show normal size & number of melanosomes in both mela nocytes & keratinocytes. Our cases differ frorn BecLers nevus in both clinical & histopatholcgic characteristics.
