Introduction and objectives: Bladder pheochromocytoma is a rare tumor and accounts for less than 0.1% of all bladder tumors. Herein we report an unusual case of bladder pheochromocytoma treated by laparoscopic partial cystectomy.
Materials and methods: A 63-year-old female with previous urothelial carcinoma of urinary bladder presented to our clinic for regular follow-up. Cystoscopy revealed one protruding mass at anterior wall of urinary bladder. Pelvic magnetic resonance imaging revealed one submucosal mass, measuring about 4.6 x 3.6 cm. The patient received laparoscopic partial cystectomy with 5-trocar method.
Results: The whole procedure was successfully performed via transperitoneal laparoscopic approach without conversion to open surgery. A 3-trocar method was conducted in this patient. Total operative time was 105 mins. Total intraoperative blood loss was 50 ml. Time to oral imtake was 26 hours. Total hospital stay was 4 days. Immunohistochemical stain showed positive results for chromogranin A, synaptophysin and CD56 while negative results for cytokeratin, S-100 protein and TTF-1. Pheochromocytoma was confirmed by pathological report. Convalescence was uneventful for this patient.
Conclusion: Laparoscopic partial cystectomy is a technically feasible option for patients with bladder pheochromocytoma.
