Telangiectasias are small, widened blood vessels on the skin. They are usually harmless, but may be associated with several diseases.
Vascular ectasias: Spider veins
Telangiectasias may develop anywhere within the body. But they are most easily seen on the skin, mucous membranes, and whites of the eyes. Usually, they do not cause symptoms. Some telangiectasias bleed and cause significant problems. Telangiectasias may also occur in the brain and cause major problems from bleeding.
Sclerotherapy is the treatment for telangectasias on the legs. Laser treatment is typically used to treat telangectasias of the face.
