Medical Definition of VITILIGO
: a progressive skin disorder that is a form of leukoderma caused by the localized or generalized destruction of melanocytes and marked by sharply circumscribed white spots of skin
Skin disorder manifested by smooth, white spots on various parts of the body. Though the pigment-making cells of the skin, or melanocytes, are structurally intact, they have lost the ability to synthesize the pigment. The reason for the condition is unclear. Individuals with vitiligo (about 1% of the adult population) are usually in good general health, but vitiligo presents a cosmetic problem that can be serious in dark-skinned individuals. Normal skin color rarely returns, and there is no known cure.
