Vitiligo is a skin pigment disorder characterized by smooth, white patches in the skin. Vitiligo is caused by the loss of pigment-producing cells in the skin (melanocytes). The white patches are very sensitive to the sun.
There is no cure for vitiligo. Treatment may include covering smaller patches with long-lasting dyes, light-sensitive drugs, in addition to ultraviolet A light therapy, corticosteroid creams, and depigmentation of the remaining skin.
