Paraganglioma of the Urinary Bladder

Abstract

Paraganglioma of the urinary bladder is a rare tumor accounting for less than 0.06% of bladder tumors and approximately 10% of extraadrenal pheochromocytomas. The symptoms at presentation may include hematuria and hypertensive crises resulting from catecholamine excess provoked by micturition or over-distention of the bladder. Most instances of the disease are hormonally active. We report a case of paraganglioma of the urinary bladder in a 49-year-old man who presented with an incidentally detected bladder tumor, which was successfully treated with partial cystectomy.
