Abstract
We report a case of solitary fibrous tumor of the pleura (SFT) which recurred 9 years after the initial operation. The patient was a 67-year-old male with a chief complaint of growing mass lesions on chest computed tomography (CT). He had undergone resection of benign SFT originating from the parietal pleura of the right thoracic cavity in October, 1995. Nine years later, a repeat chest CT revealed two enlarged pleural-based lesions in the right thoracic cavity. Under right thoracotomy, resection of the tumors including the pericardium was performed. Pathologic examination was consistent with the recurrence of benign SFT with no malignant transformation. We concluded that even though no malignant findings were shown on SFT histopathologically, patients should be followed up with long-term radiological examination.
