Vitiligo (pronounced "vit-il-eye-go") is a skin condition in which a loss of pigment causes the skin to appear white (depigmentation). Irregular white patches may occur on any area of the body. Due to the difference between the affected and unaffected areas, this condition is more visible in people with darker skin. It affects 1% to 2% of the population and can affect anyone.
This condition can also affect mucous membranes and the retina of the eye. The hair that grows in areas affected by vitiligo may also turn white.
