It was first reported by Dr. M. T. Ota of Japan in 1939 (Wikipedia)
Women are nearly 5 times more likely to be affected than men, and it is rare among white people.
Nevus of Ota may not be congenital, and may appear during puberty.
It mainly appears on either or both cheeks, forehead, eye lids and similar pigmentation of sclera as well.
It is associated with melanomas of uvea orbit or glaucoma of the same eye..
The most common reason behind this defect is hormonal imbalance at the age of puberty (13-15yrz) mainly thyroid defect which cause increase melanin production at the specified spot..
