title: Evaluation of syncope from head and neck cancer.
abstract: Five patients suffering from recurrent syncope in association with metastatic squamous cell carcinoma of the head and neck were examined. Two patients had exhaustive diagnostic work-up for syncope, which eventually disclosed previously undiagnosed, recurrent squamous cell carcinoma. Case reports describe glossopharyngeal neuralgia, a well recognized cause of syncope in the head and neck cancer patient, characterized by acute unilateral head or neck pain preceding each syncopal episode. The literature on the diagnosis of syncope is reviewed, and the syncopal mechanisms unique to the head and neck cancer patient are analyzed and discussed. A diagnostic approach to syncope in head and neck cancer is proposed.
