Vitiligo
About Vitiligo
Vitiligo is a long-term (chronic) condition where patches of skin lose their color (pigment). This occurs when pigment-producing cells, called melanocytes, are destroyed or stop functioning.
Common Symptoms
- Patches of skin that lose their color, often appearing white or light pink
- Premature whitening or graying of the hair on the scalp, eyelashes, eyebrows, or beard
- Loss of color in the tissues lining the inside of the mouth and nose (mucous membranes)
- Color loss in the inner layer of the eyeball (retina)
Diagnosis
Diagnosis of vitiligo typically involves a physical examination of the skin, where a doctor may use a special lamp called a Wood's lamp to highlight areas of depigmentation. A doctor may also ask about medical history and family history of vitiligo or other autoimmune conditions. In some cases, a skin biopsy or blood tests may be performed to rule out other conditions or check for associated autoimmune disorders.
Causes
The exact cause of vitiligo is not fully understood, but it is generally thought to be an autoimmune condition. This means the body's immune system mistakenly attacks and destroys the melanocytes. Genetic factors are also believed to play a role, as vitiligo often runs in families.
Treatment Overview
Approaches for vitiligo may include topical creams that aim to restore skin color or control inflammation, as well as light therapy (phototherapy) using specialized ultraviolet light. Surgical options, such as skin grafting, may be considered for smaller, stable patches. Complementary approaches that are sometimes discussed include dietary changes or certain herbal remedies, although scientific evidence for their effectiveness is often limited and they should be discussed with a healthcare provider.
Prognosis & Outlook
Vitiligo is a chronic condition, and its progression can vary significantly among individuals. Complete repigmentation is not always achieved, and new patches may develop over time. While not life-threatening, vitiligo may impact quality of life for some individuals.
Types & Variants
Non-segmental (Generalized) Vitiligo
The most common type, where white patches appear symmetrically on both sides of the body. This type often progresses and spreads over a person's lifetime.
Segmental Vitiligo
Less common, this type is characterized by patches on only one side or segment of the body. It tends to start at a younger age, progress for a year or two, and then stop.
