We report on a 33-year-old woman with malignant fibrous histiocytoma of the kidney. This malignant mesenchymal tumor is indistinguishable clinically and radiologically from a renal cell carcinoma. In our patient the tumor recurred locally following nephrectomy and metastasized to the lung. Post-nephrectomy radiation and chemotherapy may not alter the poor prognosis.
