Head and neck paraganglioma (HNPGL): There are various types of head and neck paraganglioma; they may have specialized names depending on the precise location. [ 9 ] Carotid paraganglioma ( carotid body tumor): Is the most common of the head and neck paragangliomas.
A paraganglion (pl. paraganglia) is a group of non-neuronal cells derived of the neural crest.They are named for being generally in close proximity to sympathetic ganglia. ...
A gangliocytic paraganglioma is a rare tumour that is typically found in the duodenum and consists of three components: (1) ganglion cells, (2) epithelioid cells (paraganglioma-like) and, (3) spindle cells (schwannoma-like).
The most common therapies for secondary polycythemia are phlebotomies [9] and, for paraganglioma and/or somatostatinoma in this cohort of patients, surgery accompanied by antihypertensive medication. [1] HIF-2α inhibitor belzutifan led to substantial improvement of symptoms in a patient with Pacak–Zhuang syndrome. [10]
Glomus tumors are usually solitary and small lesions. The vast majority are found in the hand, wrist, foot, and under the fingernails. [3]They are often painful, and the pain is reproduced when the lesion is placed in cold water - a history of sensitivity to cold weather is also common. [6]
Carney triad (CT), named for J Aidan Carney, is considered to be a specific type of multiple endocrine neoplasia (MEN). The three classically associated tumors are a subset of gastric epithelioid leiomyosarcoma (it is now known that this subset is actually gastrointestinal stromal tumor arising from the interstitial cells of Cajal), pulmonary chondroma, and extra-adrenal paraganglioma.
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.
Ganglioneuroma (occasionally called a "ganglioma") is a rare and benign tumor of the autonomic nerve fibers arising from neural crest sympathogonia (undifferentiated cells of the sympathetic nervous system). [1]
