Although surgical treatment of patients on anticoagulation regimens is a common practice among oral and maxillofacial surgeons, unexpected and unknown coagulopathies can have devastating and catastrophic consequences for the most routine of procedures. Acquired hemophila A (AHA) is an extremely rare life-threatening bleeding disorder characterized by autoantibodies directed against circulating coagulation factor (F) VIII. The effects of acquired hemophilia A can produce catastrophic bleeding and hematomas. The effect of this uncontrolled hemorrhage post dental-alveolar surgery can mimic severe head and neck infection by causing dysphagia, odynophagia, and acute airway complications. This report describes the case of a 64 year old female who was diagnosed with acquired hemophilia A (AHA) after a routine extraction of tooth #17.
