[Report of a case of malignant vesical pheochromocytoma. Diagnosis and therapy].

Bladder pheochromocytoma is a rare, usually benign bladder tumor. An exceptionally malignant bladder pheochromocytoma is reported with more than 5 years follow-up. The study of our case, and the review of 15 other cases reported in the literature show that surgery is the only effective therapy. Partial cystectomy with regional lymphadenectomy, when feasible is the treatment of choice. Because metastatic occurrence may be late, we emphasize the importance of long term follow-up.
