**5. Conclusions**

In conclusion, PSFTs are rare pleural tumors, most of which are benign; moreover, most of them are associated with a good prognostic, with the rates of malignant lesions being under 20% of cases. Most often, they are asymptomatic, with no signs and symptoms for a long period of time, and being usually discovered at a routine chest X-ray. In our study, PSFT was most commonly found in women over 40 years of age. Most of the cases were in patients over the age of 60 years. Thoracic CT scan is the main radiological instrument used for diagnosing this disease. MRI is complementary and, in some cases, superior to a CT scan. As for the therapeutic strategy, en bloc surgical resection with negative oncological margins is the gold standard in the treatment of PSFT. Chemotherapy and radiotherapy should be used in recurrent disease or inoperable stages.
