Management of sizeable carotid body tumor: Case report and review of literature.

Carotid body tumor is a paraganglioma derived from the neural crest. It arises from the carotid body which acts as a vascular chemoreceptors and is usually located at the carotid bifurcation. Sizeable (Shamblin III, >5 cm size) tumors are large and typically encase the carotid artery requiring vessel resection and replacement. Management of such tumors carries a high risk of postoperative mortality and morbidity rates specially with regards to neurovascular complications. We report a case of sizeable tumor which was surgically removed with minimal complications.
