Abstract
- Cutaneous ossification is an unusual event, and it may be primary or secondary to either inflammatory or neoplastic processes. It is classified as primary when it occurs in the absence of a demonstrable preexisting lesion. Secondary ossifications have most commonly been reported to occur with pilomatricoma, basal cell carcinoma, acne vulgaris and melanocytic nevi (nevus of Nanta). Nevus of Nanta is a pigmented nevus associated with secondary ossification. The histopathological features of an osteo-nevus of Nanta are nests of nevus cells, and bony spicules are observed beneath a melanocytic nevus. We report here two cases of osteo-nevus of Nanta.
