Telangiectasia

Alternate Names : Vascular ectasias

Definition

Telangiectasias are small blood vessels on the skin. They are usually meaningless, but may be associated with several diseases.

Telangiectasias may develop anywhere within the body but can be easily seen in the skin, mucous membranes, and whites of the eyes. Usually, they do not cause symptoms. However, some telangiectasias bleed and cause significant problems. Telangiectasias may also occur in the brain and cause major problems from bleeding.

Alcohol use
Aging
Sun exposure
