Telangiectasia
Vascular ectasias; Spider veins
Telangiectasias are small, widened blood vessels on the skin. They are usually harmless, but may be associated with several diseases.
Causes
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.
Causes may include:
- Rosacea
- Aging
- Genetics
- Pregnancy
- Sun exposure
- Varicose veins
Diseases associated with this condition include:
-

Telangiectasias of the skin occur in multiple conditions. Thin skin secondary to long-term steroid use or aging, collagen vascular disease, and hormonal variation (particularly estrogen) are all implicated in the formation of telangiectasias.
