title: [Malignant fibrous histiocytoma of the perirenal tissue: report of a case--a statistical study of 58 cases of urological malignant fibrous histiocytoma in Japanese literature].
abstract: A 78-year-old man was admitted in June 18, 1982 with a two-year history of general fatigue and loss of appetite. Physical examination revealed a child's head sized, firm, not tender, right upper quadrant mass which had an almost smooth surface and had respiratory displacement. Preoperative diagnosis was a hypovascular renal tumor presenting at the lower part of the right kidney. Right nephrectomy was performed on July 6, which displayed a specimen 1,300 g and 17 X 12 X 10 cm. The light yellow tumor appeared between the renal parenchyma and large fatty masses. The tumor was histologically diagnosed as storiform-pleomorphic malignant fibrous histiocytoma (MFH) and disclosed infiltration of both the fibrous renal capsule and adjacent perirenal fatty tissue. There was no invasion of the tumor into the renal parenchyma and the case was considered to arise from the fibrous renal capsule or the perirenal tissue. Although he had been treated with ifosfamide and adriamycin three times after operation and with immunotherapy of 3 g of PSK per day for about five months, he died three years and one month after operation. We reviewed 58 cases of MFH arising from the retroperitoneum and genitourinary tract (urological MFH) in the Japanese literature.
