Synonyms of Vitiligo

Vitiligo is a dermatological condition characterized by the appearance of white patches of skin on different parts of the body as a result of the destruction of the cells that make pigment (melanocytes). This may vary from one or two white spots on the skin to large areas of depigmentation. Vitiligo is not contagious. It seems to occur more often among people who have certain autoimmune diseases. For some people, although not for everyone, the depigmentation is progressive.
Vitiligo is characterized by spots on the skin with decreased pigmentation. These lesions are usually sharply demarcated with increased coloring (hyperpigmentation) on the borders, and are often symmetrical in shape. These areas most often appear on the face, neck, hands, abdomen, and thighs although they can occur on all parts of the skin. The hair in vitiliginous areas is usually white and the skin lesions appear white under a Wood's light. The lesions are prone to sunburn and should be protected from sunlight.
People with vitiligo may have premature graying of the scalp hair, eyelashes, eyebrows, and beard.
For some people, the depigmentation begins with a few patches and then spreads to other parts of the body. Some people notice additional depigmentation during periods of physical or emotional stress. However, in some cases, the disorder does not appear to be progressive, and the depigmentation does not spread from the areas first noticed.
The exact cause of vitiligo is not known, although there are several theories. Research on this is continuing.
There appears to be a hereditary component in some cases. Although it often appears with no family history, the probability of developing vitiligo is somewhat higher for children in families where it has been known to occur. However, people who have vitiligo often have children who are not affected by it, and many people with vitiligo do not have a family history of the disorder.
This disorder appears to be more common among people who have certain autoimmune diseases. These are diseases in which a person's immune system for some reason perceives the body's own tissues as foreign and reacts against them. Some of the diseases that are sometimes associated with vitiligo include hyperthyroidism, pernicious anemia, alopecia areata, and adrenocortical insufficiency. Research at the National Institutes of Health indicates that vitiligo is 10 to 15 times more common in people with other autoimmune diseases. The disorder may also follow unusual trauma, especially to the head.
Worldwide, about one to two percent of the population has the disorder at any one time. Although vitiligo can affect people at any age, 95 percent of those affected develop the disorder before age 40.
Most standard therapy consists of sensitizing a depigmented area with a topical or oral medication (psoralens) after which the treated area is exposed to the sun or ultraviolet light. Small lesions of Vitiligo may be camouflaged with cosmetic creams. Para-aminobenzoic acid solution or gel gives protection against sunburn.
The National Vitiligo Foundation, see below, maintains a formulary of safe cosmetics designed particularly for persons with vitiligo.
