Osler-Weber-Rendu syndrome is also known as what?

Osler-Weber-Rendu syndrome is commonly known as Hereditary Hemorrhagic Telangiectasia (HHT). This genetic condition leads to abnormal blood vessel formation, resulting in telangiectasia—small, dilated blood vessels that can be seen on the skin and in mucous membranes—and arteriovenous malformations (AVMs) in various organs, which may cause bleeding. The connection between the names lies in the clinical presentation and the hereditary nature of the condition, where affected individuals can have spontaneous nosebleeds and other bleeding complications due to these vascular malformations.

In this context, the other choices refer to different medical conditions that are not related to Osler-Weber-Rendu syndrome. Familial Hypercholesterolemia pertains to a genetic condition characterized by high cholesterol levels, Marfan Syndrome is a connective tissue disorder that affects various systems in the body, and Euler’s Syndrome is not a recognized clinical condition in medical literature related to vascular malformations and bleeding. Thus, the terminology of Hereditary Hemorrhagic Telangiectasia is fitting and widely accepted to describe Osler-Weber-Rendu syndrome.
