Purpose of review A vagal paraganglioma is a rare head and neck tumor arising from the paraganglionic tissue within the perineurium of the vagus nerve, anywhere along the course of the nerve. Due to its proximity to the internal carotid artery, the internal jugular vein and the lower cranial nerves, this disorder poses ...

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.

Pheochromocytoma and Paraganglioma.
New England Journal of Medicine, 2019Pheochromocytoma and Paraganglioma Pheochromocytoma and paraganglioma are related tumors that differ mainly in location; pheochromocytomas are adrenal, and paragangliomas can be anywhere else.

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 ...

Six cases of upper intestinal gangliocytic paraganglioma, five in the duodenum and one in the jejunum, are reported. Three histologic patterns, each comparable to patterns in paraganglioma, ganglioneuroma, or carcinoid-islet cell tumor, are mixed in varying proportions.

Paraganglioma of the thyroid gland is a rare neoplasm. Only eight cases have previously been reported. The neoplasm was confined to the thyroid in all but two patients; laryngeal involvement was seen in one and tracheal involvement in another. A review of these previously reported cases is presented along with the details of an additional case with ...

Paragangliomas of the CNS are relatively rare. Cases of location in the pineal and pituitary glands, cerebellopontine angle, cauda equina and filum terminale are known. In our neurosurgical unit a 42-year-old male patient with a history of vertigo and a generalized seizure underwent an operation for a fronto-temporal tumour.

Paragangliomas are neoplasms that arise from neural crest cells and histologically resemble their adrenal counterpart, the phaeochromocytoma. The majority of extra-adrenal tumours develop within the abdomen and are associated with the coeliac, superior and inferior mesenteric ganglia, which run parallel to the aorta.

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.

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
