hereditary hemorrhagic telangiectasia

Hereditary hemorrhagic telangiectasia is a disorder of angiogenesis, which means the process of forming new blood vessels does not occur normally. This condition leads to arteriovenous dilatations where abnormal connections are made between arteries and veins. These changes often result in cutaneo-mucosal hemorrhagic telangiectasias, which are small, red spots seen on the skin and mucous membranes. In addition to these visible changes, people with this condition may experience vascular shunting in internal organs. This means that blood flow can bypass the normal capillary system, which may affect the function of internal organs. The condition is also known by various other names, including HHT and Osler-Weber-Rendu disease.

People with hereditary hemorrhagic telangiectasia often have small red spots or telangiectasias on the skin, especially on the lips, face, and fingers. These spots may bleed easily due to the fragile nature of the abnormal blood vessels. The condition can also involve abnormal blood flow in internal organs, although detailed information about other symptoms is limited.

Hereditary hemorrhagic telangiectasia is caused by a disorder in the process of angiogenesis, leading to the formation of abnormal blood vessels. While genetic factors may play a role, specific genes linked to the condition are not provided in the available information.
