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]

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 ...
