A 62-year-old man was admitted with a chief complaint of general malaise. Computed tomography showed a large mass adjacent to the parenchyma of the left kidney. The mass was 17X13X12 cm in size. Preoperative diagnosis was left renal cell carcinoma and left radical nephrectomy was performed. Histopathologically, the tumor was diagnosed as malignant fibrous histiocytoma (MFH), and the tumor was considered to have arisen from the renal capsule. There has been no recurrence for 7 months postoperatively. We review 40 cases of MFH arising from the kidney or the renal capsule in the literature.
