Chemodectoma, paraganglioma of glomus caroticum or carotid glomus tumor occurs in the population with an incidence

of 1:30 000. The tumor is macroscopically, microscopically and biologically very similar adrenal pheochromocytoma. An important feature

of these tumors is their rich vascularization. Among the most blood supply tumors at all. Histologically, alveolar described arrangement

of tumor cells, in contrast to pheochromocytoma, sharply demarcated from each other soft tissue with broad stripes capillaries and cells

like Schwann cells. The cytoplasm of tumor cells is a major weakly eosinophilic and finely granular. Nuclei of cells may be pleomorphic and

hyperchromic, but must be stated that nuclear atypia is not unequivocal sign of malignancy. Biologically they are mostly benign tumors.

Clinically, it is a slow-growing, painless, firm and globular in shape for the angle of the mandible. Although chemodectomas were found

is generally considered to be radiosensitive, the main therapeutic approach is surgical extirpation of the tumor.
