title: Malignant pheochromocytoma of urinary bladder.
abstract: Herein is reported a fifth case of malignant pheochromocytoma of the urinary bladder. Pheochromocytoma represents only 0.4 per cent of bladder tumors with 5 to 10 per cent being malignant. A review of the 4 previously reported cases plus our own suggest that iliac-hypogastric lymphadenectomy should be considered in all cases of pheochromocytoma of the bladder. Early establishment of the malignant potential of these tumors coupled with aggressive surgical treatment improves prognosis.
