Surgical carotid body tumor

Carotid body tumors are relatively rare. In 1743, Von haller first noticed that the carotid body was considered a small gland. In 1891, Marchond reported that the carotid body tumor was surgically treated and died 3 days after the operation. By 1969, more than 500 cases of carotid body tumors had been reported. The carotid body is mostly located at the bifurcation of the common carotid artery, has an envelope, is of variable size, is about 3.5mm in diameter, and is rich in blood vessels and nerves. The blood is supplied by the small branch of the common carotid artery, and the nerves come from the cervical sympathetic ganglia, glossopharyngeal nerve, vagus nerve and hypoglossal nerve. Carotid body tumors are visually observed as reddish-brown, round or oval, with lobes and outer envelopes. The cells are mainly polygonal, with cytoplasmic eosinophilic staining, containing many vacuoles and microsomes. Occurs in 30 to 40 years old, with a malignant change rate of 5% to 10%.
