A Case of Nevus of Nanta: CASE REPORT
A 26-year-old Korean woman presented to our outpatient clinic who had suffered from a small asymptomatic pigmented nodule on the right of her forehead for several months. There was no evidence of Albright’s hereditary osteodystrophy or Gardner’s syndrome in either the patient or her family. On the physical examination, 0.5 x 0.5 cm sized, relatively well defined, brownish nodule was seen on the right of her forehead (Fig. 1). It gave the clinical impression of an intradermal nevus. The lesion was excised totally for histopathologic examination.

Nests of nevus cells were observed in the entire dermis, and rounded ossification was in the base of intradermal nevus (Fig. 2). Fat tissue was located within the central chamber of the osteoma (Fig. 3).
