Abstract
Paraganglioma (PGL) usually presents as the elevation of blood pressure and metabolic changes in patients, and its common symptoms are persistent or paroxysmal hypertension. However, some patients have no typical clinical symptoms, such as patients with non-functional PGL. Therefore, the present study reviewed the literature and summarized the present rare case to provide more accurate and in-depth help for clinical diagnosis and comprehensive treatment. The case was a 64-year-old female with epigastrium malaise for 1 year and aggravation for 7 days. Contrast-enhanced CT revealed that the soft tissue of the irregular mass was in the front of the kidney on the right abdomen with a clear boundary and the size was ~6.5x5.4x6.6 cm. Large vessels were observed in the interior and edge of the lesion. The present study prepared for retroperitoneal tumour resection according to the diagnosis of PGL. After the operation, the patient recovered smoothly and was discharged from the hospital. As of March 2023, the general condition of the patient is good.

Abstract
RATIONALE Solitary fibrous tumors (SFT) is a rare mesenchymal tumor originating from a CD34-positive dendritic mesenchymal cell, most of which is benign, the most common sites is pleura and mediastinum, and rarely in the bladder. The clinical manifestations are mainly related to the tumor volume. When the tumor volume is large, it will compress the surrounding tissues or organs and cause corresponding symptoms. Laparoscopic Incision biopsy is effective means for diagnosing SFT. PATIENT CONCERNS A 70-year-old female patient was admitted to the hospital with a bladder neoplasm detected by computed tomography scan after experiencing intestinal obstruction 3 days following esophageal cancer surgery. She denied any history of tumor disease. DIAGNOSES No abnormality was found in the physical examination and laboratory testing after admission. Ultrasound imaging showed a large solid mass with low echogenicity in the bladder. Urological computed tomography with 3D reconstruction revealed a large cystic-solid mass located on the right wall of the bladder, measuring approximately 6.8 cm × 7.1 cm × 6.5 cm, with uneven density and mild inhomogeneous enhancement after contrast administration. Cystoscopy revealed a large mucosal bulge on the right wall of the bladder and laparoscopic exploration revealed a smooth-surfaced round mass, approximately 7 cm in size. INTERVENTIONS Incision biopsy was performed to make a clear diagnosis, and appropriate tissue specimens were obtained for pathological testing. OUTCOMES The patient was diagnosed as SFT according to pathology. The patient was followed up for 6 months after surgery, and no recurrence was observed. LESSONS SFT occurring in the bladder are extremely rare, and the site is scarcely reported in the relevant literature; thus, it is easy to misdiagnose and laparoscopic incision biopsy may be a good choice.

Abdominal nonfunctional paraganglioma in which succinate dehydrogenase subunit B (SDHB) immunostaining was performed: a case report. J Med Case Rep 2023; 17:106. [PMID: 36945070 PMCID: PMC10031891 DOI: 10.1186/s13256-023-03822-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 02/14/2023] [Indexed: 03/23/2023] Open
Abstract
BACKGROUND Abdominal nonfunctional paraganglioma is rare. Malignant potential of paraganglioma is assessed by Grading of Adrenal Pheochromocytoma and Paraganglioma score and genetic testing, but genetic testing is not common. We present a case of abdominal nonfunctional paraganglioma whose malignant potential was assessed by grading of adrenal pheochromocytoma and paraganglioma score and succinate dehydrogenase subunit B staining alternative to genetic testing. CASE PRESENTATION A 39-year-old Japanese man had a right retroperitoneal tumor without symptoms. Uptake in the tumor was shown by 123I-meta-iodobenzylguanidine scintigraphy. There were no metastases. The results of biochemical workups including blood hormones and urinary metanephrines were normal. We performed retroperitoneoscopic surgery. The tumor was positive for chromogranin A staining but negative for tyrosine hydroxylase. On the basis of the preoperative biochemical workups and pathology results, we diagnosed the tumor as nonfunctional paraganglioma. The Grading of Adrenal Pheochromocytoma and Paraganglioma score classified the tumor as moderately differentiated. Furthermore, negative succinate dehydrogenase subunit B staining suggested the patient has the SDHx (SDHA, SDHB, SDHC and SDHD) mutation. CONCLUSION Abdominal nonfunctional PGLs are associated with SDHB mutation, and SDHB staining should be performed as a screening.

Abstract
Urine cytology is an economical and convenient method of triaging patients who present with urinary symptoms as well as surveying those who have previously been diagnosed with urothelial carcinoma for recurrent or persistent disease. While the vast majority of malignancies diagnosed in urine cytology are urothelial carcinomas, it is important to recognize nonurothelial elements to inform patient prognosis and raise the possibility of involvement by a urothelial carcinoma variant, nonurothelial malignancy of the bladder, or a nonbladder primary, which may alter patient management pathways. As such, becoming familiar with morphologic features of nonurothelial malignancies in urine cytology as well as their related clinical risk factors, radiologic and cystoscopic features, differential diagnostic considerations, and the utility and pitfalls of ancillary tests can facilitate optimal patient care.

Abstract
Introduction: Paraganglioma of the urinary bladder is a rare but well-documented tumour. Herein, we provide the largest, comprehensive systematic review of the literature and aim to increase familiarity with this rare but significant neoplasm. Methods: A systematic review of the literature was conducted on the NCBI PubMed database. The search criteria were not limited to any specific years or languages. There were 418 articles between January 1953 and August 2020, of which 255 case reports were selected. Results: Paragangliomas of the urinary bladder most commonly occurred in Caucasians in the fifth decade of life, most commonly presenting with haematuria and variations of ‘micturition attacks’. Eighty percent of tumours were functionally active. The mucosa was normal in 91% of patients. In all, 25% of tumours were treated with transurethral resection alone, 65% had partial cystectomy and 5% had radical cystectomy. Alpha-blockers were administered pre-operatively in 38% of patients and the risk of intra-operative hypertensive crisis was over three times greater in those who did not receive an alpha-blocker. The tumour was confined to the bladder in 75% of cases. Metastasis occurred in 20% of cases, most commonly to iliac nodes. The mean follow-up time was 26.5 months. In cases that documented follow-up, 18.6% had recurrence, most commonly in lymph nodes and bone. Conclusion: All patients presenting with micturition attacks or haematuria with a computed tomography showing an enhancing, well-defined submucosal bladder lesion and/or cystoscopy showing a lesion with normal overlying mucosa should be worked up for a possible paraganglioma of the urinary bladder. Level of evidence: Not applicable

Abstract
Abstract
Background
Paraganglioma of the urinary bladder is a very rare benign tumor that constitutes less than 0.5% of all bladder tumors. It can be functional and non-functional. Functional tumors present with symptoms of catecholamine excess, and non-functional tumors usually remain asymptomatic.
Case presentation
Here, we present a case of non-functional urinary bladder paraganglioma in a 36-year-old female who presented to us with a history of intermittent hematuria. The routine hematological and biochemical parameters were within normal limits. Diagnostic computed tomography (CT) revealed a hypervascular lesion in the urinary bladder dome with no significant uptake in gallium-68-labelled-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid peptides-NaI3-octreotide positron emission tomography (DOTA-NOC PET/CT). Histopathology and immunohistochemistry confirmed the diagnosis of paraganglioma.
Conclusion
We present this case because of the rare location of paraganglioma in the urinary bladder and being non-functional with low/absent somatostatin receptor expression.

Abstract
BACKGROUND Nonfunctional bladder paragangliomas is a rare urological disease. It may present clinical, radiology and pathological features similar to bladder cancer, Only scarce reports have been reported. Urologist must identify this generally benign neuroendocrine neoplasm to avoid misdiagnosis. CASE PRESENTATION A 62-year-old female presented the outpatient department of our hospital with the symptoms of stomachache, frequent micturition, and urination pain for 20 days. Diagnosed with high blood pressure 1 year ago, administered Amlodipine besylate tablets 5 mg po qd occasionally, did not check blood pressure; denied any tumor observation in the family history. Color ultrasound of the urinary system showed a 38 mm × 34 mm hypoechoic mass on the right side of the bladder, CDFI: in the masses, blood supply was sufficient. Cystoscope showed bladder occupying lesion. Biopsy diagnosis: papillary polypoid cystitis was suspected as a malignant change (Fig. 3a). Then, the patient was admitted to our urological department. Further, computer tomography urography considered bladder cancer. Cystoscopy and biopsy failed to define the nature of the lesions in our outpatient department, which prompted a transurethral resection of the bladder tumor. histopathological and immunohistochemical results were diagnosed as bladder paragangliomas. For the reason, the tumor was removed by partial resection of the bladder. The postoperative recovery and follow-up were uneventful. CONCLUSIONS Nonfunctional bladder paragangliomas are occasionally found on imaging studies with the symptoms of urinary tract infection or/and intermittent painless hematuria. It may present clinical, radiology and pathological features similar to bladder cancer, so knowledge of this generally benign neuroendocrine neoplasm is of great importance to avoid misdiagnosis. It should be accompanied by the clinical and pathological characteristics of the patient and image changes. Partial resection of the bladder can effectively treat this disease.
