Nevus of Ota is an oculo-dermal melanocytosis presenting as blue-black or gray-brown diffuse pigmentation [Figure 1]. It commonly occurs unilaterally in areas innervated by the first two divisions of trigeminal nerve [Figure 2]a. Nevus of Ota appears at birth and has a female preponderance. It may be associated with nevus of ito, ocular melanoma (1 in 400), and glaucoma (10.3%). Nevus of Ito is a similar pathologic process to nevus of Ota which presents as unilateral pigmentation over the supraclavicular, deltoid, and scapular regions [Figure 2]b. Although usually an isolated lesion, nevus of Ito rarely accompanies nevus of Ota as portrayed in this case [Figure 2]c.
