[Solitary fibrous tumor of the parietal pleura resected by video-assisted thoracic surgery; report of a case].
A 35-year-old male was admitted to our hospital for further examination of abnormal shadow on chest X-ray. Contrast-enhanced chest computed tomography (CT) showed a clear-shaped tumor with homogenous enhancement, measuring 25 x 20 mm in size, which had enlarged, compared with chest CT of 2 years before. The tumor appeared to be based partially on the parietal pleura. Under the diagnosis of solitary fibrous tumor (SFT) originated from the visceral or parietal pleura, video-assisted thoracic surgery (VATS) was performed. Under thoracoscopy, the tumor was pedunculated and arose from the parietal pleura. The tumor was resected completely. The pathologic findings revealed proliferation of spindle cells and collagen fibers without malignant aspects. Immuno-histochemical findings showed positive immunostaining for CD34 and vimentin in the tumor cells. These findings confirmed that the tumor was SFT.
