1 Vitiligo is a disease in which the pigment cells of the skin, melanocytes, are destroyed in certain areas. 2  Vitiligo results in depigmented, or white, patches of skin in any location on the body. 3  Vitiligo can be focal and localized to one area, or it may affect several different areas on the body.
Any location on the body can be affected, and most people with vitiligo have white patches in many areas of the body. Melanin is the pigment that gives the skin its characteristic color. Vitiligo is caused by a loss of pigment in the skin, due to destruction of pigment-forming cells known as melanocytes. Although vitiligo affects all races equally, it is more noticeable in dark-skinned people. Vitiligo can cause cosmetic problems.
