A Case of Halo Congenital Nevus / 대한피부과학회지

ABSTRACT

A halo nevus is a pigmented nevus surrounded by a depigmented zone. It usually occurs in childhood or adolescence. Depigmented zone may form around a variety of acquired melanocytic lesions of neuroectodermal origin, including nevocellular nevi, blue nevi, spindle and epithelioid nevi, primary and metastatic melanomas, and neurofibromas. The occurrence of a halo around congenital melanocytic nevi has rarely been reported. We report a case of halo congenital nevus in a 11-year-old girl.
