Vitiligo is a skin condition in which there is a loss of color (pigment) from areas of skin. This results in uneven white patches that have no pigment, but the skin feels normal.
Autoimmune disorder - vitiligo
Vitiligo occurs when immune cells destroy the cells that make brown pigment (melanocytes). This destruction is thought to be due to an autoimmune problem. An autoimmune disorder occurs when the body's immune system, which normally protects the body from infection, attacks and destroys healthy body tissue instead. The exact cause of vitiligo is unknown.
Vitiligo may appear at any age. There is an increased rate of the condition in some families.
Vitiligo is associated with other autoimmune diseases:
Flat areas of normal-feeling skin without any pigment appear suddenly or gradually. These areas have a darker border. The edges are well defined, but irregular.
Vitiligo most often affects the face, elbows and knees, back of the hands and feet, and genitals. It affects both sides of the body equally.
Vitiligo is more noticeable in darker-skinned people because of the contrast of white patches against dark skin.
No other skin changes occur.
Vitiligo is difficult to treat. Early treatment options include the following:
Skin may be moved (grafted) from normally pigmented areas and placed onto areas where there is pigment loss.
Several cover-up makeups or skin dyes can mask vitiligo. Ask your provider for the names of these products.
In extreme cases when most of the body is affected, the remaining skin that still has pigment may be depigmented, or bleached. This is a permanent change that is used as a last option.
It is important to remember that skin without pigment is at greater risk for sun damage. Be sure to apply a broad-spectrum (UVA and UVB), high-SPF sunscreen or sunblock. Sunscreen can also be helpful for making the condition less noticeable, because unaffected skin may not darken in the sun. Use other safeguards against sun exposure, such as wearing a hat with a broad rim and long sleeve shirt and pants.

The course of vitiligo varies and is unpredictable. Some areas may regain normal pigment (coloring), but other new areas of pigment loss may appear. Skin that is repigmented may be slightly lighter or darker than the surrounding skin. Pigment loss may get worse over time.
Contact your provider for an appointment if areas of your skin lose their coloring for no reason (for example, there was no injury to the skin).
