A Case of Nevus of Nanta

ABSTRACT

Nevus of Nanta is a pigmented nevus associated with secondary ossification. We describe a case of nevus of Nanta with no evidence of Albright's hereditary osteodystrophy. A 26-year-old Korean woman presented with a small asymptomatic brownish nodule on the right forehead. Histopathologic examination revealed nests of nevus cells in the dermis. Round ossification was in the base of intradermal nevus.
