Syncope caused by carotid sinus syndrome due to malignancy of the head and neck is rare. The aim of this paper is an inspection into current knowledge of this syndrome, its clinical characteristics, differential diagnosis and current treatment modalities.

Syncope based on carotid sinus hypersensitivity caused by a malignant process of the neck region is a significant diagnostic challenge for any clinician. Neck tumor is rarely thought of, since its frequency is rare in the general population. The disease is mostly recognized in the advanced stages when episodes of syncope are more frequent.
