Paraganglioma in the bladder wall: A case report

Abstract

Background: Pheochromocytomas are tumors originating from chromaffin cells and producing catecholamines. In 10%-20% of cases, these tumors act outside of the adrenal medulla, defining conglomerates named paragangliomas. Bladder paraganglioma is a rare tumor and accounts for less than 0.06% of all bladder neoplasms and less than 1% of all pheochromocytomas, with the first case described in 1953. The clinical procedure given by 47%-77% of the overall number of cases, consists of headache 48.1%, tachycardia 43.4%, hypertension 54.7%, hematuria 47.2%, and visual alterations.

Case Presentation: The article reports a case of a patient whose lesion was identified in the lateral wall of the bladder during a prostate ultrasonography exam, and was subsequently treated surgically with a partial cystectomy. The aim of this study is to detail the diagnosis and treatment of a patient with bladder paraganglioma.

Conclusion: From the overall study conducted in this article, it is possible to conclude that paraganglioma requires adequate diagnostic and therapeutic methods. These methods include ultrasounds and computed tomography scans, followed by cystoscopy with visualization and biopsy of the lesion, and resection of the lesion.
