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.

Management of primary cardiac paraganglioma.
Journal of Thoracic and Cardiovascular Surgery, 2020OBJECTIVE Cardiac paraganglioma is a rare tumor that most surgeons have limited experience treating. The objective of this study is to examine the management and outcomes for cardiac paraganglioma treatment when cared for by a multidisciplinary cardiac ...

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

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.

Jugulotympanic paragangliomas are the most common tumors of the middle ear and temporal bone. Although these larger tumors can prove to be formidable, the advent of microscopic and skull base surgical techniques has greatly enhanced the ability to treat and manage these tumors.

The management of vagal paragangliomas is extremely challenging. Treatment of these lesions must be tailored individually for each patient. The best treatment modality depends on the patient's age and health and the size and extent of the tumor. This article discusses clinical presentation, multicentric and malignant vagal paragangliomas, evaluation ...
