Vitiligo Skin DisorderA common skin condition causing white patch on skin by which 2% of total population is suffering. The human skin contains special skin cells melanocytes that produce the pigment melanin which colors the skin.
In Vitiligo, the special skin cells "melanocytes" as well as the tissues (mucous membranes) that line the inside of the mouth, nose, genital and rectal areas, and the retina of the eyes are destroyed. As a result, white patches of skin appear on different parts of the body.

According to one theory, people with vitiligo develop antibodies that, turn upon them and destroy their own melanocytes instead of protecting them. There is another theory according to which the melanocytes somehow attack and destroy themselves. Finally, some people with vitligo have reported that a single event such as severe sunburn or an episode of emotional distress is the main cause of this order. Scientifically, events of this nature have not been accepted as the main cause of vitiligo. These are merely coincidences.
