Paraganglioma of the Gallbladder
Archives of Surgery, 1972What appears to be the first case of a paraganglioma arising in the wall of the gallbladder is described. As there was no symptomatology of a catecholamine-secreting neoplasm, the tumor was believed to be nonfunctional. The chromaffin reaction was inconclusive since it was performed on tissue following prolonged formaldehyde solution fixation.

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 ...

Phaeochromocytoma and Paraganglioma
2016Phaeochromocytomas and paragangliomas are relatively uncommon tumours which may be manifest in many ways, specifically as sustained or paroxysmal hypertension, episodes of palpitations, sweating, headache and anxiety, or increasingly as an incidental finding. Recent studies have shown that an increasing number are due to germline mutations. This review

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 ...

Pheochromocytoma and Paraganglioma
2009Pheochromocytomas and extra-adrenal sympathetic paragangliomas are catecholamine-secreting neuroendocrine tumors derived from the chromaffin cells of the embryonic neural crest. Parasympathetic paragangliomas are related tumors which most often arise within the head and neck, and are anatomically associated with the parasympathetic nervous system ...

European Archives of Oto-Rhino-Laryngology, 2005
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

Head & Neck, 1997
Paragangliomas are uncommon neuroendocrine tumors. In the head and neck region they are most commonly associated with the carotid body, vagus nerve, jugulotympanic paraganglia, and occasionally the superior and inferior laryngeal paraganglia. Laryngeal paragangliomas and subglottic paragangliomas are rare.

World Journal of Surgery, 2008
AbstractParaganglioma are rare chromaffin cell tumors that develop from the neural crest cells. Parasympathetic ganglia‐derived tumors are found almost exclusively in the neck and skull base and typically do not secrete catecholamines. In contrast, most sympathetic ganglia‐derived tumors are found in the abdomen and produce an excess of catecholamines.

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
