title: Acquired factor VIII inhibitor presenting as a tongue hematoma.
abstract: Acquired hemophilia is a rare disorder that has potentially disastrous consequences if not recognized and treated in the setting of acute hemorrhage. We report a case of undiagnosed acquired hemophilia due to factor VIII inhibitor in which a tongue hematoma was the chief manifestation. Diagnosis, acute management, and long-term therapeutic options are reviewed.
