Vitiligo is a disorder that causes the skin to lose its color in patches.
It is not possible to predict the extent and rate of color loss from vitiligo. It can affect any part of the body, hair, mucous membranes in the mouth (inside) and eyes. It occurs when the cells producing melanin die or stop functioning. It may appear more in people with dark skin than light skin.
This condition affects the mental status because of the way their person looks.
Treatment may improve the skin condition but there is no cure.
The main symptom of vitiligo is loss of skin color in patches. Usually, discoloration appears in the areas of skin that is exposed to sun.
Other signs and symptoms include: skin discoloration, premature whitening or graying of the hair, loss of color in the tissue that line the inside the mouth and nose, loss of color in inner layer of eyeball, change in colors in eyeball, discolored patches around armpits or rectum.
Vitiligo appears at any age but mostly at the age of 20.
Depending on the type of vitiligo, it may appear in many parts of the body (generalized vitiligo), only one side of the body (segmental vitiligo) and few areas of the body (focal vitiligo).
Vitiligo is caused when cells that produce melanin (melanocytes) fails to produce melanin (the pigment that give color to the skin) or dies.
It is still unknown why this happens but some mechanisms have been proposed:
autoimmune disorder (immune system attacks the melanocytes),
