Abstract

Nevus of Ota is a hamartoma of dermal melanocytes. Clinically, Nevus of Ota is manifested as blue or gray patch on the face; such condition is congenital or acquired and is within the distribution of branches of the trigeminal nerve. The nevus can be unilateral or bilateral. In addition to skin, it may involve ocular and oral mucosal surfaces. The case of an 18-year old female with unilateral bluish black macule on the right side of the face since birth is presented. She also had a bluish patch on the right shoulder at birth, which disappeared when she turned 10 years. The pathogenesis of Nevus is unknown, and effective treatment has been realized with pigment-specific lasers.
