Acquired Hemophilia A with Gastrointestinal Bleeding

摘要

Peptic ulcer disease is the most common cause of acute gastrointestinal bleeding, followed by variceal bleeding, Mallory–Weiss syndrome, and malignancy. On the contrary, acquired hemophilia A is a very rare hemorrhagic disease, which usually manifests with musculocutaneous bleeding, caused by autoantibodies against coagulation factor VIII.
