How can I be sure that I have vitiligo? And how do you get it?

Vitiligo. Vitiligo is a mysterious malady characterized by a loss of pigment, or skin color. If affects about one out of every hundred people. No one knows what triggers this strange condition. The most fashionable theory claims that it is one of the autoimmune disorders in which the body attacks and destroys its own tissues — in this case the pigment producing cells. For confirmation, see a dermatologist.
Depigmentation. Vitiligo is a condition where there is patchy or generalized due pigmentation of areas of skin. At present there are no treatments for repigmentation of the areas.
