Vitiligo is a disease in which the pigment cells of the skin, melanocytes, are destroyed in certain areas. Vitiligo causes white patches on your skin. It can also affect your eyes, mouth, and nose. It occurs when the cells that give your skin its color are destroyed. No one knows what destroys them. It is more common in people with autoimmune diseases, and it might run in families. It usually starts before age 40.
Symptoms: Symptoms and signs of Vitiligo include loss of skin color in the form of de-pigmented, or white, patches of skin in any location on the body. Vitiligo can be focal and localized to one area, or it may affect several different areas on the body.
Cause:The exact cause of Vitiligo is unknown, although most experts believe that it is an autoimmune condition in which the body's immune system mistakenly attacks and destroys certain cells within the body.
Most people who have Vitiligo will develop the condition prior to age 40; about half develop it before age 20.
