[A case of localized pleural mesothelioma].
A 68-year-old male with localized pleural mesothelioma was described. The tumor was removed surgically in association with left upper pulmonary lobe and regional lymph nodes, since low grade malignancy had been suggested by preoperative needle biopsy. The operative and macroscopic findings revealed that the tumor was well encapsulated and arise from visceral pleura of S3 segment of left upper lobe, projecting into pleural cavity as a pedunculated mass. The tumor measured 9 X 6 X 4 cm in diameter. Based on electron microscopic and immunohistochemical findings of the tumor, the origin of tumor cells was discussed.
