Paraganglioma of the urinary bladder: A case report and discussion of the literature

Urinary bladder paragangliomas (UBPGL) are rare neuroendocrine tumors that originate from extra-adrenal paraganglia in the bladder. We report the case of a 67-year-old patient who presented with a submucosal bladder tumor. A hypertensive crisis developed during the initial attempt at cystoscopic resection, and biopsies demonstrated a UBPGL. The importance of considering UBPGL in the differential diagnosis of submucosal bladder tumors is discussed. Appropriate perioperative blood pressure management and the choice of surgical approach can optimize outcomes and prevent morbidity.
