Angina bullosa haemorrhagica presenting as acute upper airway obstruction.

We report a case of acute upper airway obstruction caused by a rapidly expanding blood-filled bulla in the oropharynx (angina bullosa haemorrhagica), requiring tracheal intubation. The larynx could not be visualized by either awake fibreoptic laryngoscopy or direct laryngoscopy under anaesthesia. Surgical tracheostomy was therefore performed under general anaesthesia.
