Many people choose to have them removed. Removal is done by causing damage to the vessel and forcing it to collapse or scar. This reduces the appearance of the red marks or patterns on the skin.

Instead of forming on the skin, telangiectases caused by HHT appear in vital organs, such as the liver. They may burst, causing massive bleeding (hemorrhages). WHAT ARE THE SIG...
