[Acute airway obstruction in acquired hemophilia A].

We report the case of a 67 year old patient suffering from acute airway obstruction caused by hemorrhage localized to the tongue, mouth cavity and hypopharynx, with no evidence of bleeding in his history. The patient presented initially with a globus feeling of the neck, dysphagia and a sore throat. CT scan revealed a swelling of the lingual and sublingual areas and the pharyngeal wall. Next day, there was an immediate life-threatening event caused by progressive bleeding with airway obstruction and an inability to intubate requiring coniotomy. The etiology of the hemorrhage was confirmed by finding a depletion of factor VIII and the presence of auto-antibody directed against this factor. Based on this case report and a review of the literature, we discuss the diagnosis and treatment of acquired hemophilia.
