title: [A pheochromocytoma of urinary bladder treated with neoadjuvant chemotherapy].
abstract: A 69-year-old female presented with hypertension and a solid mass in the bladder on ultrasonography. Cystoscopy revealed a submucosal tumor in the right lateral wall of the bladder. A transurethral resection was performed. Histologically, pathologic examination revealed a malignant pheochromocytoma. She refused surgical therapy and radiation therapy. She had no treatment for two years. She suddenly complained of gross hematuria. T2-weighted magnetic resonance imaging showed a bladder tumor of high intensity and extra-bladder invasion. She was treated with chemotherapy (CVD) for 26 cycles. Since the tumor size was reduced, she was referred to our hospital for operative indication. Partial cystectomy was performed. Histologically, the tumor was a pheochromocytoma of the urinary bladder. Ten months after the operation, she has no clinical evidence of recurrence.
