Temporal paragangliomas (PGL) are usually limited to the paraganglionar system with a sporadic or familial origin. Familial PGL have recently been shown to be associated with germline alterations in SDH group of genes, and occasionally are associated with a variety of genetic multisystemic disorders (von Hippel-Lindau disease, multiple endocrine ...

A case of vulvar paraganglioma is reported. Following presentation with vulvar pain, a 1-cm nodule was excised from the labium minus of a 58-year-old woman. Histologically, the tumor was composed of nests of round eosinophilic cells with moderately pleomorphic nuclei, beneath an intact squamous epithelium.

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.

AbstractWe present a case of paraganglioma of the thyroid. The preoperative evaluation, surgical management, and histopathology are described. Four similar cases that have been reported are summarized, and a hypothesis for the origin of a paraganglioma within the thyroid capsule is proposed.

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 ...

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 ...

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

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

Pheochromocytomas and Paragangliomas
Endocrinology and Metabolism Clinics of North America, 2019Pheochromocytomas are rare neuroendocrine tumors. Extra-adrenal lesions arising from the autonomic neural ganglia are termed paraganglioma. Clinical symptoms are common between the adrenal and extra-adrenal forms and are determined by excess secretion of catecholamines.

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.
