Pheochromocytoma of the urinary bladder without typical symptoms.

Pheochromocytoma of the urinary bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We report, herein, the case of a 62-year-old woman with bladder pheochromocytoma. The patient presented with a bladder tumor that was incidentally found by computed tomography (CT) without the triad of sustained hypertension, hematuria and postmicturitional syncope. Cystoscopy revealed a yellowish submucosal tumor in the right lateral wall of the bladder. Treatment consisted of transurethral resection in the initial diagnosis of bladder tumor. A definitive diagnosis was made postoperatively upon pathological examination. The patient has been followed up for 12 months and has shown no recurrence.
