Abstract

 

Nevus of Ota is a dermal melanocytosis, clinically localized on skin that is innervated by the first and second branches of the trigeminal nerve. It occurs almost entirely in Asian people. This manifestation is rarely described in light-skinned non-Asian persons. We present a case of bilateral Ota nevus in a 47-year-old light-skinned non-Asian woman.

A 47-year-old light-skinned non-Asian woman presented with bilateral manifestations of nevus of Ota. The ocular hyperpigmentation was present at birth and the skin lesions appeared in early childhood. Clinically, flat blue-gray pigmentation with an irregular border was present on the skin of the lateral ocular areas. Bilaterally, the sclerae were also involved. Nasal and oral mucosa were not affected. Ophthalmologic examination showed no abnormalities. Audiometric examination was within normal limits.
