Carotid Body Tumors

Abstract
Tumors of the carotid body characteristically are slow growing neoplasms which produce symptoms as a result of pressure on contiguous structures. Most carotid body tumors are benign, but in rare instances are malignant. Angiography has aided greatly in diagnosis. Most carotid body tumors can be safely removed without interrupting the carotid circulation by utilizing the subadventitial approach. In rare instances, excision of the tumor may require artery resection with graft replacement. Twelve additional cases are reported.
