[ad. F. paragangliome (Alezais & Peyron 1908, in Compt. Rend. des Séances de la Soc. de Biol. LXV. 746): see next and -oma.]
A tumour thought to arise from a paraganglion (in its wider sense) or the adrenal medulla; esp. one of non-chromaffin tissue. Cf. phæochromocytoma.
1914Surg., Gynecol. & Obstetr. XVIII. 209/1 Whenever a tumor of a paraganglion—a paraganglioma—is suspected, it should be fixed in a solution containing chromic acid or its salts. 1925Amer. Jrnl. Anat. XXXIV. 89 By far the greater number of pathologists believe in a vascular origin for the growths of the carotid body... Some later workers would call these tumors ‘paragangliomas’. 1948Martin & Hynes Clin. Endocrinol. vii. 144 Chromaffin tumours. These uncommon tumours include the phæochromocytomata which arise from chromophile cells of the adrenal medulla, and the paragangliomata which originate from chromaffin tissue in the intrathoracic cervical chain, the carotid bodies, or the organs of Zuckerkandl. 1956H. M. Zimmerman et al. Atlas Tumors Nervous Syst. 177/1 The chromaffin tumors are found most commonly in the adrenal medulla... They are called pheochromocytomas (chromaffin tumor, functionally active paraganglioma)... The term ‘paraganglioma’ is best used for the non-secretory and hence non-chromaffin tumors of the paraganglionic tissues. 1974Passmore & Robson Compan. Med. Stud. III. i. xvii. 37/1 Glomus jugulare tumours. These are another example of non-chromaffin paragangliomata; they..grow in the connective tissue that lies between the bulb of the internal jugular vein and the floor of the middle ear.
