[A case report of primary malignant fibrous histiocytoma of the lung].
In this paper, a case of a 59-year-old female of primary malignant fibrous histiocytoma (MFH) of the lung is reported. The patient, who had dyspnea as a main complaint, presented with an abnormal shadow in the chest about 20 years ago, and rapid increase of the shadow has been recognized from one year ago. A pulmonary tumor of the left upper lobe was diagnosed by chest CT, bronchography, pulmonary arteriography. A left pneumonectomy was performed and metastases in lymph nodes and pleural dissemination were recognized. The tumor was 11 X 8 X 6 cm, white, multiple nodular, and solid with a clear border. Histologic examination showed the storiform pleomorphic type of MFH mixed with fibroblastoid cells and histiocytoid cells. Ga scintigram, bone scintigram, and CT conducted before and after the surgery did not show metastasis, but the patient died due to respiratory insufficiency caused by metastasis to the right pleura at 9 months after surgery.
