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.
