Dermatology - Nevus of Ota

Dermatology - Nevus of Ota 
Nevus of Ota is a pigmented skin abnormality that can either be present at birth or develop in early childhood or during puberty. It is prevalent among individuals of Asian heritage, however it is not exclusive to them.
The pigmentation can vary in intensity, ranging from modest to highly disfiguring. It can affect either one side or both sides of the body, and is characterized by a patchy, dark mixture of blue and brown hyperpigmentation on the skin. The condition mostly affects the skin and mucous membranes that are supplied by the first and second divisions of the trigeminal nerve. The blue coloration is caused by the existence of ectopic melanocytes within the dermis.
The diagnosis is established through clinical means.
Laser treatment is a highly effective method for addressing this disfiguring condition.
