Nevus of Ota, originally was described by Ota and Tanino in 1939 is a hamartoma (benign malformation) of dermal melanocytes. Nevus of Ota presents as a blue or gray patch on the face, which is congenital or acquired, unilateral or bilateral, and, in addition to skin, it may involve ocular and oral mucosal surfaces.
Nevus of Ito, initially described by Minor Ito in 1954, is a dermal melanocytic patch affecting the supraclavicular, deltoid, or scapular regions. Nevus of Ito often occurs in association with nevus of Ota in the same patient but is much less common
Q-switched laser treatment is unquestionably the current treatment of choice for nevi of Ota and Ito and it works via selective photothermal and photomechanical destruction of dermal melanocytes and melanophages
