Carotid body tumor overview

Overview
Among the nonchromaffin paragangliomas, the carotid body tumor is second in frequency to the glomus jugulare tumor. Despite the large number of published cases, these tumors are relatively uncommon. Several authors have suggested that the carotid body tumor represents a proliferative response of the normal organ to some unknown disturbance within the nervous system, rather than a true neoplasm.
