• Cho YO
• Han KS

Abstract

The nevus of Ota is a distinctive, mesodermal pigmentation of the facial skin commonly combined with pigmentation of the eye, usually congenital but capable of benign progression. It is usually unilateral, but in the 1st of these 2 cases, pigmentation of the facial skin and the eye was bilateral and associated with pigmentation of the left shoulder and the anterior cervical area(nevus of Ita). In the 2nd of these 2 cases, pigmentation of the eye and the shoulder was bilateral. Pigmentation of the eye accompanies that of sclera in every case, that of conjunctiva, iris and choroid in some case. It accompanies that of optic disc rarely, but in the 1st of these 2 cases, the pigmentation of optic disc was found in both eyes, in the 2nd, in the right eye. We have experienced the above-mentioned 2 cases of nevus of Ota associated with nevus of Ito which accompanied the pigmentation of optic disc, that are rare. We briefly reviewed the literature relating to nevus of Ota and Ito.
