title: Contacting metastasis of a fibrous tumor of the pleura.
abstract: A 26-year-old female with a fibrous tumor of the pleura that metastasized to the other site of the pleura due to contact is reported. The primary lesion was a 6-cm pedunculated tumor originating from the diaphragm; the metastasis was a broad-based 1-cm tumor located on the parietal pleura of the lateral thoracic wall, within an area in contact with the primary tumor. The surrounding pleura around the small tumor and the diaphragm-the area that contacted the large tumor-was resected with both of the tumors under a thorascope. Despite a benign pathologic finding, a localized fibrous tumor of the pleura can then metastasize to the pleura due to contact. It was concluded that, because localized fibrous tumors of the pleura can occasionally metastasize to the area in contact with tumors, the intrathoracic cavity should be thoroughly observed using a thoracoscope.
