Telangiectasias are small blood vessels just below the surface of the skin. The blood vessels are very visible through the skin. They may appear as a single vessel or as many vessels in clusters.
They may also be seen in the mouth or whites of the eyes. The may also be in other locations, such as the brain and the back of the eyes.
Telangiectasias are caused by small blood vessels that are stuck in a wide open position. There is no clear reason for why this happens in many cases.
Some telangiectasias are due to conditions like:
- Chronic sun and/or cold exposure
- Basal cell carcinoma
- Cushing’s syndrome
- Hereditary hemorrhagic telangiectasia
- Injury from surgery or radiation
- Too much estrogen—can be caused by oral contraceptives or pregnancy
