Non-functional muscle-invasive bladder paraganglioma-a case report.

ABSTRACT:

Background

Extra-adrenal pheochromocytoma (paraganglioma) of the urinary bladder is a rare tumor, accounting for 0.05% of bladder tumors and less than 1% of all paragangliomas. In the genitourinary tract, paragangliomas are most commonly found in the bladder. These tumors have aggressive malignant potential, so complete surgical resection for localized disease is important. Paragangliomas may be non-functional or functional with catecholamine secretions. Although these tumors are rare and difficult to distinguish from urothelial carcinoma (UC), intraoperative manipulation of these tumors may lead to a catecholamine surge and intraoperative complications. Preoperative or early intraoperative recognition of this tumor would facilitate appropriate alpha blockade to minimize morbidity.
