What is vitiligo?
Vitiligo (vit-il-EYE-go) is a skin disorder that causes the skin to lose its color. Smooth white areas (called macules if less than 5mm or patches if 5mm or larger) appear on a person’s skin. If you have vitiligo in a place that has hair, the hair on your body may also turn white.
The condition occurs when melanocytes (the skin cells that produce melanin, the chemical that gives skin its color, or pigmentation) are destroyed by the body’s immune system.
What are the types of vitiligo?
Vitiligo can be:
Generalized, which is the most common type, when macules appear in various places on the body.
Segmental, which is restricted to one side of the body or one area, such as the hands or face.
Mucosal, which affects mucous membranes of the mouth and/or the genitals.
Focal, which is a rare type in which the macules are in a small area and do not spread in a certain pattern within one to two years.
Trichome, which means that there is a white or colorless center, then an area of lighter pigmentation, and then an area of normally colored skin.
Universal, is another rare type of vitiligo, and one in which more than 80% of the skin of the body lacks pigment.
