Malignant fibrous histiocytoma (MFH) is now considered the most common soft tissue sarcoma in adults, but MFH arising from the renal capsule is very rare. A 77-year-old woman was admitted with a painful mass in the left flank region on September 10, 1986. Preoperative diagnosis was hypovascular retroperitoneal tumor in contact with the upper pole of the right kidney. The tumor was removed together with the right kidney on December 18, 1986, and the specimen weighted 640 gm. Histological examination revealed storiform-pleomorphic malignant fibrous histiocytoma. No postoperative adjuvant therapy was carried out. Local recurrence of the disease was found about 9 months after the operation, and the patient died on February 23, 1988. Fifteen cases with MFH arising from the kidney reported in the Japanese literatures are reviewed, and the diagnosis, treatment, prognosis and tumor marker are discussed.
