Pheochromocytoma is rare tumor usually arising within the adrenal medulla or in any location where chromaffin tissue may exist. About 10% of pheochromocytoma may occur in extraadrenal lesions and 10% of the bladder has the clinical triad of hematuria, hypertension, and syncope during or immediately after urination. The only criteria of malignanr potential is the demonstration of chromaffin cells in an organ such as lung, liver, bone and lymph node which normally does not contain them.
We report a case of malignant pheochromocytoma of the bladder in 50-yr-old female paient who was taken operation for total cystectomy and ileal condiut 2 year ago. On readmission, high level of catecholamine and it´s metabolite in serum and urin are suggestive of recurrence or metastasis, and the multiple metastases to the 2nd lumber vertebra, left 11th rib and hip bone are found by Gallium-scannning.
