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.
Causes of Vitiligo. 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. The exact cause of the destruction of these cells is not known. One possible explanation might be that the body's immune system destroys the cells, as in other autoimmune conditions.
