A Case of Nevus of Nanta / 대한피부과학회지

ABSTRACT

Nevus of Nanta is a melanocytic nevus with secondary ossification. Many theories involving external stimuli have been proposed to explain this rare condition; however, the origin of the ossification within the melanocytic nevus remains unknown. A 70-year-old woman presented with an asymptomatic solitary skin-colored papule with a central depression on the right malar area for one year. Histopathologic examination revealed an intradermal nevus with bone trabeculae. We herein report an interesting case of nevus of Nanta.
