Nevus of Ota with associated palatal involvement.

The nevus of Ota is a macular discoloration of the face which is most commonly found in the Japanese. The sclera is also often affected. The oral cavity is less commonly involved in the Japanese and is rarely affected in non-Orientals. The present case is only the seventh reported in a non-Oriental patient with clinical oral involvement and the first to illustrate the histopathologic features of an oral-lesion.
