    They usually secrete hormones and estimates of a familial history vary. [1] [2] Nonchromaffin paragangliomas are usually benign. [3] They are generally present at the head and neck, most often at carotid body or jugulo-tympanic, they rarely secrete hormones and commonly have a familial history. [1] [2]

    It can be the source of paraganglioma. [8]The organ of Zuckerkandl is of pathological significance in the adult as a common extra-adrenal site of pheochromocytoma though the most common extra-adrenal site is in the superior para-aortic region between the diaphragm and lower renal poles.

    Glomus tumors were first described by Hoyer in 1877 while the first complete clinical description was given by Masson in 1924. [5] Histologically, glomus tumors are made up of an afferent arteriole, anastomotic vessel, and collecting venule.

  9. Neuroendocrine tumor - Wikipedia

    en.wikipedia.org/wiki/Neuroendocrine_tumor

    Neuroendocrine tumors, despite differing embryological origin, have common phenotypic characteristics. NETs show tissue immunoreactivity for markers of neuroendocrine differentiation (pan-neuroendocrine tissue markers) and may secrete various peptides and hormones. There is a lengthy list of potential markers in neuroendocrine tumors; several ...
