Abstract: Background/aim: The aim of the present study was to evaluate the etiology and clinical and pathological behavior of solitary fibrous tumors of the pleura (SFTPs), as well as the most appropriate surgical approach and the results of long-term follow-up of this condition. Materials and methods: Clinical and long-term follow-up records of 14 patients who had surgery for SFTP between 2001 and 2014 were reviewed retrospectively. Etiological factors, diagnostic procedures, and clinical courses and outcomes for these patients were studied. Results: Of the 14 patients, 8 were male (57%) and 6 were female (43%) patients. The mean age was 54.14 ± 10.35 (41?75) years. There was no remarkable common etiological factor. Preoperative diagnosis was achieved only in 2 patients. Predominant symptoms were cough and chest pain. Complete resection was achieved in all patients. Video-assisted thoracic surgery (VATS) was performed in 8 patients. All but one patient were classified as having benign SFTP. The mean follow-up was 58.5 ± 41.4 (10?132) months and no recurrence was noted in the follow-up. Conclusion: These rarely seen tumors of the pleura are usually benign and asymptomatic and their preoperative diagnosis is difficult. Clinical and pathological behavior is still unpredictable and the treatment consists of complete resection. Minimally invasive techniques such as VATS are recommended for surgery if the tumor size is appropriate.
