Acquired Hemophilia A: Rare Cause of Upper Airway Hematoma and a Literature Review.

Background: Acquired hemophilia A (AHA) is a rare blood disorder with high morbidity and even mortality as severe bleeding can occur in up to 90% of affected patients. Unlike congenital hemophilia which presents with intra-articular bleeding, acquired hemophilia causes bleeding into the skin, muscle, mucous membranes and soft tissues.

Case Presentation: We report an unusual case of upper airway hematoma in a 61-year-old man who presented with acute onset dysphagia and shortness of breath.
