Malignant Fibrous Histiocytoma (MFH) usually arises from the extremities with the retroperitoneum being the second most common site. We present the case report of a 58-year-old man presenting with fever and was detected to have a renal mass on evaluation. He underwent a radical nephrectomy with a preoperative diagnosis of renal cell carcinoma. But the final histopathological report was MFH. Primary renal MFH is extremely rare and is usually diagnosed on histopathology with the aid of immunohistochemistry.
恶性纤维组织细胞瘤（MFH）通常起源于四肢，腹膜后是第二常见的发病部位。我们报告一例58岁男性病例，该患者因发热就诊，评估时发现有肾肿块。他接受了根治性肾切除术，术前诊断为肾细胞癌。但最终组织病理学报告为MFH。原发性肾MFH极为罕见，通常借助免疫组织化学通过组织病理学诊断。
