Even though they are benign, after their complete resections malignant recurrences might be seen in follow up period. In this study, based on our case series undergone complete surgical resection due to SFT, we looked for an answer whether if it is convenient to accept these tumors as benign or not.

Materials and Methods: Patients undergone surgery between January 2000 and January 2011 were included in this study. Follow up data, patients and tumor histopathological characteristics were analysed.

Results: Our series consisted of 14 cases (eight male, six female) with a mean age of 49.5 ± 15.3 (15-70 years). All patients" undergone thoracotomy, and complete resection was performed. The mean follow-up was 50.3 ± 30.6 months (between 9 -101 months). Two recurrences were detected and both patients died due to recurrent disease.

Conclusions: Though they are considered to be benign lesions, SFT have a potential to come along with malignant recurrences. Recurrences were observed in giant tumors and this makes us think if it is possible to overlook a malignant focus in histopathological observation in such kind of big tumors. In this sense, patients should be informed in this regard and a complete and wide resection should be performed as much as possible with a long time follow up period as malignant diseases.
