organ of Zuckerkandl


- paraganglioma / pheochromocytoma

  • Chromaffin-reacting pheochromocytomas of the adrenal medulla are the most frequently encountered functional paraganglionic neoplasms. However, extra-adrenal pheochromocytomas as well as non-chromaffin paragangliomas, including those of the carotid body and glomus jugulare, may produce symptoms from catecholamine secretion.
  • One of the extra-adrenal sites from which these tumors arise is from a collection of para-aortic, paraganglion cells around the origin of the inferior mesenteric artery.
  • This collection of paraganglia was described in fetuses by Zuckerkandl in 1901 and has subsequently been referred to as the organ of Zuckerkandl.
  • The diagnosis and management of these neoplasms differ somewhat from that of adrenal pheochromocytomas, but excellent results are often obtained by excision of these lesions.
