BACKGROUND: Paraganglioma (extra-adrenal pheochromocytoma) of the bladder is a very rare disease, accounting for 0.06% of all bladder tumors. Optimal management of bladder paraganglioma before kidney transplantation is unknown. We report a case of partial cystectomy for urinary bladder paraganglioma before living kidney transplantation. CASE PRESENTATION: A 59-year-old man with a 27-year history of hemodialysis was referred to our department for further examination of a bladder tumor detected during pre-transplantation testing...

Paragangliomas and pheochromocytomas are rare catecholamine secreting neoplasms that arise in the extra-adrenal autonomic paraganglia and adrenal medulla, respectively. Although typically presenting with paroxysms of headaches, palpitations, diaphoresis and hypertension, a broad spectrum of clinical manifestations may occur. Diagnosis relies on biochemical studies followed by adequate imaging investigation. Cross sectional morphological and functional imaging modalities have improved diagnostic accuracy and are crucial in the surgical planning...

INTRODUCTION: Paraganglioma is an extremely rare catecholamine-producing tumor during pregnancy. Paraganglioma carries high risks of fetal and maternal mortality during pregnancy. We report a pregnant woman with paraganglioma in the second trimester. CASE DESCRIPTION: A 24-year-old pregnant woman presented with severe hypertension in the 17th week of gestation. Hormonal examination and Magnetic Resonance Imaging (MRI) confirmed the diagnosis of extra adrenal pheochromocytoma (paraganglioma)...

Pheochromocytomas and their extra-adrenal counterpart paragangliomas (PGLs; together called PPGLs), belong to the family of neural crest-derived tumors. Given the overexpression of a wide variety of specific targets in PPGLs, it seems that these tumors are optimally suited to be imaged by specific radiopharmaceuticals. Thus, theranostics approaches with somatostatin agonists and antagonists are rapidly evolving in the setting of these tumors and may be considered as the next step in the therapeutic arsenal of metastatic PPGLs...

Context: Pheochromocytomas (PCCs) are tumors that are derived from the chromaffin cells of the adrenal medulla. Extra-adrenal PCCs called paragangliomas (PGLs) are derived from the sympathetic and parasympathetic chain ganglia. PCCs secrete catecholamines which cause hypertension and have adverse cardiovascular consequences as a result of catecholamine excess. PGLs may or may not produce catecholamines depending on their genetic type and anatomical location. The most worrisome aspect of these tumors is their ability to become aggressive and metastasize, for which there are no known cures...

Pheochromocytoma is a neoplasm, which develops from cells of the chromaffin tissues that are derived from the ectodermic neural system and mostly situated within the adrenal medulla. Approximately 15% of pheochromocytoma cases arise from extra-adrenal chromaffin tissue. Pheochromocytoma of the bladder is rare and accounts for less than 0.06% of all bladder neoplasms and less than 1% of all pheochromocytomas. We report a case of a young woman who presented with uncontrolled hypertension, recurrent urinary tract infections and micturition attacks and was found to have a metastatic bladder paraganglioma...

OBJECTIVE: Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors derived from adrenal or extra-adrenal locations, respectively. Upon suspicion of PPGL, specific metabolomic, molecular, biochemical, imaging, and histopathologic studies are performed to prove, localize, treat, and monitor disease progression. Improved diagnostic tools allow physicians to accurately diagnose PPGL, even in patients presenting with small (<1 cm) or biochemically silent tumors, which previously delayed proper detection and treatment...

CONTEXT: Pheochromocytoma and paraganglioma are rare neuroendocrine tumors which overproduce catecholamines and arise from the adrenal gland or extra-adrenal chromaffin cells of the sympathetic and parasympathetic ganglia (1). Excessive catecholamine-induced stimulation of cardiac myocytes leads to damage which manifests in several forms ranging from Takotsubo to dilated cardiomyopathy. Diagnosis of pheochromocytoma-related cardiomyopathies is often delayed due to the atypical presentation associated with many cases...

Pheochromocytoma (PHEO) and paraganglioma (PGL) are rare catecholamine-producing neuroendocrine tumors arising from adrenal medulla or extra-adrenal sympathetic and parasympathetic ganglia. Most of the PHEOs/PGLs are benign tumors, but metastatic disease is common, especially in patients with particular genetic background. Although PHEOs/PGLs were described more than a century ago, diagnosis and therapy of metastatic disease are still challenging. Advances in understanding molecular and metabolic changes associated with tumorigenesis lead us to identification of the background of these tumors...

Pheochromocytomas are rare tumors derived from chromaffin cells located in the adrenal and extra adrenal tissues. Pheochromocytomas are diagnosed biochemically and localized using different imaging modalities. The definitive management is surgical resection. Brown adipose tissues are normally present during fetal development, with regression over time. Brown adipose tissues are thermogenic and usually located in the neck, mediastinum, and retroperitoneum. Here, we report a case of a unilateral pheochromocytoma surrounded by brown fat...

Objective Pheochromocytoma and paraganglioma (PPGLs) are rare neuroendocrine tumors derived from the adrenal medulla or extra-adrenal paraganglioma from extra-adrenal chromaffin tissue. Although malignant PPGLs has miserable prognosis, the treatment strategy remains to be established. An internal radiation therapy using [(131)I]meta-iodobenzylguanidine ((131)I-mIBG) called MIBG therapy has been attempted as one of the systemic treatment of malignant PPGLs. The aim of this study is therefore to evaluate the safety and the efficacy of MIBG therapy for refractory PPGLs...

BACKGROUND: Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors of the adrenal glands and paraganglia, occurring sporadically or as a range of hereditary tumor syndromes. About 30% of PPGLs are attributed to germline mutations. Clinical presentation, including localization, malignant potential, and age of onset, varies depending on the genetic background. Genetic testing for PPGLs is not well studied in Southeast Asia. We reviewed clinical management of PPGLs in Singapore, highlighting current gaps in clinical practice...

Ectopic pheochromocytoma (EP) is considered as pheochromocytoma located at extra-adrenal site. Surgical removal is believed to be the best choice for treatment of pheochromocytoma. We present a series EP resected by laparoscopic approach (LEP) and confirm its feasibility. We retrospectively reviewed clinical data of 4 patients underwent laparoscopic resection of LEP (periaortocaval EP, n = 1; retroperitoneal EP, n = 2; bladder EP, n = 1), which was collected and analyzed retrospectively in Zhejiang Provincial People's Hospital...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

BACKGROUND AND PURPOSE: Factors associated with malignancy in patients with pheochromocytoma (adrenal tumors, Pheo) and paraganglioma (extra-adrenal, PGL) are not well-defined and all patients require lifelong surveillance. The primary aim of our study was to determine genetic and clinical variables associated with malignancy in patients with Pheo/PGL. METHODS: Single institution retrospective review was performed of all patients who underwent surgery (1/95-1/15) for Pheo/PGL...

PURPOSE: Paraganglioma, a kind of pheochromocytoma originating from embryonic neural crest, is a rare neuroendocrine neoplasm commonly located at extra-adrenal areas such as head, neck, and abdomen. There are a few reports on renal paragangliomas; fewer than 5 reported cases are renal pelvic paragangliomas, including our case. METHODS: Our patient, who had not experienced headache, hypertension, or palpitation, was founded to have a fixed mass in the left renal pelvis incidentally...

We report the case of a 48-year old woman where probably the intramuscular administration of glucocorticoids by an orthopedist induced a pheochromocytoma crisis. The development of a cardiogenic shock with a cardiac arrest made the use of a venoarterial extra corporeal membrane oxygenation (VA-ECMO, Cardiohelp®, Maquet, Rastatt) necessary. To treat a pulmonary edema under VA-ECMO an Impella-CP® (Abiomed, Aachen) was implanted. A coronary angiography, endomyocardial biopsies and a computer tomography were performed...

INTRODUCTION: Although few studies have demonstrated utility of18 F- fluoro-2-deoxy-d-glucose positron emission tomography/computerised tomography (18 F-FDG PET/CT) in benign pheochromocytoma/paragangliomas (PCC/PGLs), there limited data on factors predicting the FDG uptake in PCC/PGL. METHODS: The study was conducted at a tertiary health care centre. In addition to the routine investigations, all patients (n = 96) with PCC/PGL were evaluated with18 F-FDGPET/CT and majority (n = 78) underwent131 I-metaiodobenzyl guanidine (131 I-MIBG) scintigraphy...
