BMJ Case Reports, 2023
A man in his 70s, with a history of a glomus jugulare paraganglioma diagnosed 18 years ago, presented with an unprovoked deep vein thrombosis (DVT). The paraganglioma had been treated by radiotherapy, and yearly scans had not shown any progression since treatment.

Radiotherapy of paragangliomas
Clinical Otolaryngology, 1984From 1964 to 1980 28 patients with extensive paragangliomas were treated with radiation therapy. Nine patients had a carotid body tumour and 19 had a temporal bone tumour. During the 16 year period the radiation dose was gradually reduced from 60 Gy in 6 weeks to 40 Gy in 4 weeks. Continuous tumour control was achieved in all patients (follow-up 1.5-18

Background: Paragangliomas are groups of neuroendocrine neoplasms originating from neural crest cells throughout the body, but are rarely observed within the orbit. Case report: Two patients, a 4-year-old male and 27-year-old female, presented with a slow-growing proptosis.

Paragangliomas are unusual tumors that are sometimes familial. We treated a family who exhibited multiple head and neck paragangliomas (HNPGs) and pheochromocytomas. The purpose was to determine the clinical characteristics of paragangliomas with familial history and to define a better standardized proceeding in the management of these tumors. Patients

Between 1967 and 1990 inclusive, 28 patients with paragangliomas of the neck were diagnosed at the University of Alabama at Birmingham Affiliated Hospitals. There were 11 men and 17 women, whose ages ranged from 12 to 76 years (mean, 47 years). Tumor locations included the carotid bodies (19 cases), the vagus nerves (three), supraglottic larynx (two ...

The paraganglia are derived from neural crest cells and arise in association with autonomic ganglia throughout the body. Glenner and Grimley’ divided the extraadrenal paraganglion system on an anatomic and histologic basis into several groups: 1) branchiomeric paraganglia, closely related to arteries and cranial nerves in the head and neck and superior

Pheochromocytoma and Paraganglioma
Endocrine Practice, 2015Pheochromocytomas (PHEOs) and paragangliomas (PGLs) are neural crest cell tumors associated with catecholamine production and assessed by a metanephrine/methoxytyramine measurement. This review summarizes the genetics of these tumors.Case presentation, review of the relevant literature, and bullet point conclusions.Genetic research over the past 10 ...

The relationship between altitude and the development of paragangliomas (PGLs), rare tumors within the sympathetic nervous system has been suggested since the early 1970's. Here, we discuss how altitude, marked by lower barometric pressure and hypoxia (reduced oxygen partial pressure), may influence cancer rates.

A study of gangliocytic paragangliomas (GPs) of the gastrointestinal tract from 51 patients showed characteristic microscopic features: epithelioid cells with an endocrine growth pattern, spindle cells, and ganglion cells. Forty-nine tumors were located in the duodenum, 1 in the jejunum, and 1 in the pylorus.
