Vitiligo is a long-term skin condition characterized by patches of the skin losing their
pigment. The patches of skin affected become white and usually have sharp margins. The hair
from the skin may also become white. The inside of the mouth and nose may also be involved.
Typically both sides of the body are affected . ] Often the patches begin on areas of skin that are
exposed to the sun. It is more noticeable in people with dark skin. Vitiligo may result
in psychological stress and those affected may be stigmatized.
The exact cause of vitiligo is unknown. It is believed to be due to genetic susceptibility that is triggered by an environmental factor such that an autoimmune disease occurs.
Risk factors include a family history of the condition or other autoimmune diseases, such
as hyperthyroidism, alopecia areata, and pernicious anemia. It is not contagious. Vitiligo is
classified into two main types: segmental and non-segmental. Most cases are non-segmental,
meaning they affect both sides; and in these cases, the affected area of the skin typically expands
with time. About 10% of cases are segmental, meaning they mostly involve one side of the body;
and in these cases, the affected area of the skin typically does not expand with time. Diagnosis
can be confirmed by tissue biopsy.
