“…In the genitourinary tract, renal pelvis (4.9%) is the third primary site of paragangliomas, following behind the bladder (79.2%) and urethra (12.7%) (2). It has been reported that 97% of paragangliomas were considered benign and occurred more frequently in women between 30 and 40 years of age (3).…”

“…Paraganglioma originating from chromaffin-producing neural crest tissue is usually located at the site of distal aortic bifurcation associated with the sympathetic chain. In the genitourinary tract, renal pelvis (4.9%) is the third primary site of paragangliomas, following behind the bladder (79.2%) and urethra (12.7%) (2). It has been reported that 97% of paragangliomas were considered benign and occurred more frequently in women between 30 and 40 years of age (3).…”

“…It has been documented that surgical operation was the most optimal treatment for renal pelvic paraganglioma, functional or nonfunctional (8). Notably, α-receptor antagonist should be administered to stabilize hypertension before operation and avoid hypertensive crisis occurring throughout the surgical procedure when patients are suspected to have functional paragangliomas (2).…”

The patient was a 24-year-old man who had a left renal mass noted incidentally during a medical examination at the People's Hospital of China Three Gorges University (Yichang, China) in March 2016. Ultrasonography performed on the patient showed a left kidney mass (9.4 × 5.9 cm) located in the site of left renal pelvis with blood signs. Nevertheless, he had no history of headache, sweating, hypertension, or lumbar pain, and laboratory examinations included routine blood urinary, function of liver and kidney, and serum catecholamine indicated no abnormality. He was admitted.A plain computed tomography (CT) scan of the patient's upper abdomen demonstrated a heterogeneous mass (7.6 × 5.9 cm) in the left renal area involving the pelvicalyceal system (Fig. 1A). Contrast-enhanced CT results showed an increasing heterogeneous density of the mass, which compressed the left renal parenchyma with distinct border after injection of iodine-containing solution (Fig. 1B). Moreover, CT angiography indicated that the rates of both renal glomerular filtration and renal blood reperfusion were normal.Based on these tests, the patient was diagnosed with a left renal pelvic tumor provisionally and underwent left radical nephrectomy by transperitoneal laparotomy. At operation, the mass was at the middle and lower pole of the left kidney, involving the renal pelvis. Renal artery was then interim blocked and radical excision of the left kidney was done owing to the tumor being almost in the renal parenchyma. Notably, the cut section showed a chocolate brown part measuring 9 × 5 × 4.5 cm in the renal pelvis and another brown

“…In the bladder, it can produce symptoms typical of pheochromocytoma, including hematuria and micturition syncope resulting from the release of catecholamines by bladder contraction. In 10-15% of cases, paragangliomas of the bladder are nonfunctioning; another 10% show hormonal activity without clinical expression ( 4 ) .…”

Neuroendocrine neoplasms of the urinary bladder are a rare type of tumor that account for a small percentage of urinary bladder neoplasms. These tumors of the urinary bladder range from well-differentiated neuroendocrine neoplasms (carcinoids) to the more aggressive subtypes such as small cell carcinoma. Despite the rarity of the neuroendocrine tumors of the bladder, there has been substantial investigation into the underlying genomic, molecular, and the cellular alterations within this group of neoplasms. Accordingly, these findings are increasingly incorporated into the understanding of clinical aspects of these neoplasms. In this review, we provide an overview of recent literature related to the 2016 World Health Organization Classification of Neuroendocrine Tumors of the Urinary Bladder. Particular emphasis is placed on molecular alterations and recently described gene expression. The neuroendocrine tumors of the urinary bladder are subdivided into four subtypes. Similar to their pulmonary and other extrapulmonary site counterparts, these have different degrees of neuroendocrine differentiation and morphological features. The clinical aspects of four subtypes of neuroendocrine tumor are discussed with emphasis of the most recent developments in diagnosis, treatment, and prognosis. An understanding of molecular basis of neuroendocrine tumors will provide a base of knowledge for future investigations into this group of unusual bladder neoplasms.
