A rare case of ovarian paraganglioma was incidentally found as a 1.2-cm intraovarian mass in a 68-year-old hypertensive female operated for an endometrial carcinoma. Histologically, it was arranged in characteristic Zellballen composed of polygonal clear cells with a granular cytoplasm that expressed diffusely CAM5.2 cytokeratin, chromogranin, neuron ...

Phaeochromocytoma and paraganglioma
Journal of Clinical PathologyPhaeochromocytomas and paragangliomas are rare catecholamine-producing neuroendocrine tumours which can potentially cause catastrophic crises with high morbidity and mortality. This best practice article considers the causes and presentation of such tumours, screening and diagnostic tests, management of these patients and consideration of family ...

AbstractNon-secreting paragangliomas are rare tumours usually present in the head and neck. We describe an unusual case of familial paraganglioma with cranial nerve palsies. After exhaustive investigation, a vagal paraganglioma was found and excised. The positive family history of paraganglioma was of significance, although this was only present in one

Extra-adrenal pheochromocytomas and paragangliomas are rare tumors of neural crest origin, most commonly found in the retroperitoneum. Because these tumors are so uncommon, relatively little is known about their natural history. Comparisons between adrenal pheochromocytomas and extra-adrenal pheochromocytomas have appeared in the medical literature ...

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.

Aorticopulmonary paraganglioma
General Thoracic and Cardiovascular Surgery, 2011We describe a 61-year-old woman with an anterior mediastinal paraganglioma. The patient complained of a chronic cough that had lasted about 6 months. Her chest computed tomography (CT) showed a highly enhanced mediastinal tumor in the aorticopulmonary window. We surgically resected this tumor thorough a left anterior thoracotomy.

Spinal paragangliomas (SP) are benign and overall rare extra-adrenal neuroendocrine tumors often diagnosed during workup for lower back pain. Complete surgical resection achieves both symptomatic relief and cure. We present a 32-year-old man with a longstanding history of lumbago and bilateral lower extremity pain found to have a lumbar paraganglioma ...

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

Phaeochromocytoma and paraganglioma
Baillière's Clinical Endocrinology and Metabolism, 1993Use of current analytical techniques should lead to the successful diagnosis of most catecholamine-secreting tumours, and the experience and confidence which has evolved with the use of HPLC-ECD for plasma and urinary catecholamine estimation, as well as their greater diagnostic sensitivity and specificity, should soon render the older urinary assays ...

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.
