Acquired haemophilia A (AHA) is a rare autoimmune disorder resulting from antibodies against coagulation factor VIII. AHA causes severe, unexpected bleeding which may be life-threatening and should be considered when a patient with no previous history of bleeding presents with spontaneous bleeding and a prolonged APTT. This case report describes onset of AHA of a 75-year-old male who was admitted to Vejle Hospital with acute need for intubation due to breathing and swallowing problems caused by supraglottic haematoma. The case was complicated by anticoagulant treatment with rivaroxaban.
