Malignant fibrous histiocytoma (MFH) is a primitive sarcoma originating in the deep soft tissue and composed of fibrocytic and histiocytic cells in a storiform pattern. It is rare but the most common soft tissue sarcoma of adulthood. MFH occurred in various epithelial organs derived from the supportive mesenchymal elements. The lung represents an extremely rare primary site. We have experienced one case of MFH, arising in the lung parenchyme in 67 years old male patient with cough for 6 months. The patient was taken right upper lobe and right middle lobe lobectomy with good post-operative results. But another MFH was recurred in the left upper lobe 3 months after complete resection. So he had been treated with chemotherapy and radiofrequency ablation of tumor. Then he continued to be treated with chemotherapy
