Telangiectasias are abnormally dilated blood vessels associated with a number of diseases.

Vascular ectasias

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 readily and cause significant problems. Telangiectasias may also occur in the brain and cause major problems from bleeding.
