흉막에 발생한 국소성 섬유성 종양

Localized fibrous tumor of the pleura (LFTP) is of submesothelial fibrous origin, which has been called pleural fibroma and has been confused with mesothelioma. We experienced a case of LFTP in a twenty nine year old man. The tumor arose from the right parietal pleura with long stalk. Chest X-ray and CT scan showed a 6$\times$5$\times$4cm well-defined mass in the right costophrenic angle. Wo evidence of metastasis was noted. Exploratory thoracotomy with enbloc excision of 6$\times$5$\times$4cm mass was done. The fine needle aspiration cytology and histopathologic features indicated the tumor to be malignant, and biologic behavior was discussed.
