Recurrent Solitary Fibrous Tumor of the Mediastinum / 대한흉부외과학회지

ABSTRACT

Solitary fibrous tumors of the serosal cavities are rare and usually occur in the visceral or parietal pleura, but they have also been observed in the mediastinum, pericardium, peritoneum, lung parenchyma, orbit, and the meninges. The histological variability of these tumors may contribute to the difficulty in diagnosing these neoplasms, especially when they arise in the mediastinum and extrathoracic sites. The clinical behavior of the tumor is unpredictable. Some tumors that appear histologically benign may behave aggressively. The incidence of aggressive behavior is variously reported as between 13 and 23% of cases in most large series. This report is a case review in a 53-year-old female patient who had re-excision of histologically benign, recurrent solitary fibrous tumor, 1, 6, 11, and 14 years after the initial operation.
