Most cases are sporadic, rare family clusters have been reported  and are characterized as being unilateral (95%, having a female predilection (80%, displaying scleral lesions (65%), and being congenital (60%) . The lesions were composed of brown and blue macules the size of wich varied from that of a grain of rice to that of lentil. The overall pigment picture varied from deep purplisch-blue to light brownish-blue . Lesions tend to be slate-gray to brown in color with a ‘powder-blast burn' appearance. The forehead, temple, periorbital area, cheek, and nose are commonly involved. Rarely, pigmentation is bilateral and large areas of the face and oral mucous membranes are affected . The nevus of Ota is a misnomer because it does not contain true nevus cells and derives its pigmentation from dendritic melanocytes which are found in the reticular layer of the dermis . The treatment options for this condition included cryotherapy, dermabrasion, surgical excision and cosmetic camouflage. Although The Q-switched lasers have been used successfully to treat nevus of Ota .
