Nevus of Ota and Ito

Nevus of Ota and Ito are blue gray patches on the face and shoulder, respectively consisting of pigment in the dermis suggesting that these pigments have remained in the dermis instead of the epidermis where they are normally found. These lesions can either be congenital or acquired and are common in Asian population. Lasers, especially those in the “red” such as the Alexandrite and Ruby and even the Nd:YAG have been effective in removing the misplaced melanocytes (pigment cells) in the dermis, thus lightening the blue/gray patches.
