The first case of simultaneous presentation of a bladder and renal pelvic malignant fibrous histiocytoma is reported. Although only a small percentage of fibrous histiocytomas are malignant the lesion is extremely aggressive. Radiotherapy and chemotherapy have been used but only sporadic remissions have been reported. If the tumor is localized wide surgical excision is recommended.
