(kē'mō-dek-tō'mă),
Aortic body, carotid body, chemoreceptor, or glomus jugulare tumor; nonchromaffin paraganglioma; receptoma; a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies; consisting histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveoluslike pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. Compare: paraganglioma.

Neoplasms of these cells are termed chemodectomas or nonchromaffin paragangliomas (JOHNSON, 1968; CAPEN, 2002), and are frequently described in the aortic and carotid bodies of domestic animals (CAPEN, 2002).
Paragangliomas traditionally are divided into chromaffin paragangliomas (associated with the sympathetic nervous system) and nonchromaffin paragangliomas (associated with the parasympathetic nervous system and derived from structures presumed to function as chemoreceptors).
