title: Solitary Fibrous Tumor - Less Common Neoplasms of the Pleural Cavity.
abstract: OBJECTIVE
  solitary fibrous tumors (SFT) represent a heterogeneous group of primary pleural neoplasms with a low incidence rate and of which the biological origin, which consists of mesenchymal cells, is uncertain.
  
  
  METHODS
  The authors present herewith a retrospective analysis of 22 patients with SFTs who were diagnosed and surgically treated between the years 2000-2015. The preoperative tumors were successfully verified morphologically by transthoracic core needle biopsy under CT control in 27.3% of patients. Surgical approaches were either posterolateral thoracotomy or videothoracoscopy. The follow-up median was 45 months (range 1-188 months).
  
  
  RESULTS
  Twenty tumors were surgically removed radically, two tumors were found to be unresectable due to the considerable tumor size. From histological point of view 81.8% of tumors were SFT with low malignant potential, 18.2% of tumors with high malignant potential. Despite the radical extirpation of the SFT, it relapsed in two patients.
  
  
  CONCLUSIONS
  The gold standard of SFT treatment is radical surgical removal; however, patients at risk of recurrence require additional follow-ups. The results of adjuvant therapy in recurrent and malignant forms of SFTs are the subject of discussion and further study.
