[A case of localized fibrous mesothelioma arising from visceral pleura of the right lower lobe].
A 56-year-old male who had been followed for chronic hepatitis had cough and hemosputum. Chest X-ray and CT films showed an abnormal mass shadow in the right thorax. On suspicion of intrathoracic tumor, resection was performed. The tumor, which was on the diaphragm without invasion, was pedunculated and arose from the bottom surface of visceral pleura of the right lower lobe. From the microscopic findings and immunohistochemical staining, the tumor was diagnosed as localized fibrous mesothelioma. Some localized fibrous mesothelioma exhibit as malignant tumor. Therefore, complete resection and intensive follow-up should be done.
