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. The clinical manifestations are usually unilateral; only 5% of cases are bilateral. In this article, due to rarity of the case, a 15-year-old patient, who was diagnosed with bilateral ota nevus, without having any dermatological complaints other than cosmetic appearence and stains in her eyes and around was presented.
