Vitiligo is a chronic autoimmune disorder that causes patches of skin to lose color or pigment, resulting in white spots. It occurs when the body's immune system attacks and destroys melanocytes, the skin cells that produce melanin, the pigment that gives skin its color. The white patches can appear anywhere on the body, but are most common on the face, neck, hands, and in skin creases. They can also appear symmetrically on both sides of the body, or on one side of the body in a less common subtype called segmental vitiligo. In addition to skin, vitiligo can also affect hair, eyes, and the inner ear: I copied all of this from Google
