A chest X-ray film of a 66-year-old man with cough and sputum indicated a mass lesion in the left middle lung filed. Thoracotomy revealed a tumor in the left upper lobe, invading to the left main bronchus, the parietal pleura, the pericardium and the left atrium. A left pneumonectomy was performed with partial resection of the parietal pleura, the pericardium and the left atrium. The histological diagnosis of this tumor was malignant fibrous histiocytoma of the lung. One month after the operation he began to complain of melena and fever. Gastroscopy revealed a hemorrhagic tumor with massive coagulum in the corpus of the stomach. Since the histology of the gastric tumor was the same as that of the pulmonary tumor and the chest X-ray film of the previous year showed a coin lesion in the left middle lung field, it was assumed that the pulmonary tumor had metastasized to the stomach. The patient had died of pneumonia two months after the operation. Primary malignant fibrous histiocytoma of the lung is very rare. Only 14 cases of primary malignant fibrous histiocytoma of the lung have previously been reported in the literature. Primary malignant fibrous histiocytoma of the lung with metastasis to the stomach has never been reported in the literature.
