Ultrastructure of malignant paraganglioma of organ of Zuckerkandl. 1978

I Damjanov, and A E Chang, and J N Blechner, and J Foster

Electron microscopic study of a malignant paraganglioma of the organ of Zuckerkandl revealed similarities between the tumor and the normal paraganglia. The well-differentiated portion of the tumor recapitulated the structure of the basic functional units of the paraganglion. In addition there signs of anaplasia both at the histologic and ultrastructural level. Large neurosecretory granules were noted in some of the tumor cells, but most of the cells were agranular. Crystaloids resembling those seen in alveolar soft part sarcoma were also noted. The study supports the theory on the common origin and histogenesis of paragangliomas and alveolar soft part sarcomas.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010220	Para-Aortic Bodies	Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.

D010236	Paraganglioma, Extra-Adrenal	A relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the CAROTID BODY; GLOMUS JUGULARE; GLOMUS TYMPANICUM; AORTIC BODIES; and the female genital tract. It consists histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels.
