摘要
hereditary hemorrhagic telangiectasia is an autosomal dominant disease in which arteriovenous communications are typically seen in the skin, mucosal surfaces, lungs, brain and gastrointestinal tract. this disease typically presents as epistaxis, gastrointestinal bleeding and arteriovenous malformations (in the brain and lungs). although the epistaxis and gastrointestinal bleeding can result in anemia, patients diagnosed with hereditary hemorrhagic telangiectasia rarely present severe anemia. herein, we report the case of a 49-year-old man with severe anemia and undiagnosed hereditary hemorrhagic telangiectasia.
