Surgical treatment of recurrence of solitary fibrotic soft tissue tumor

Solitary fibrous tumor (SFT) is a rare neoplasm of mesenchymal origin comprising less than 2 % of all soft tissue tumors. SFT was first described in 1931 by J.H. Kerry who found it in the pleura. Then this tumor was found in various anatomical areas including soft tissues. Considering the absence of standardized methods of treatment for this pathology and radiation and chemotherapy ineffectiveness, surgical treatment is the method of choice. Despite its benign nature, SFT can be aggressive and lead to metastases requiring comprehensive approach to treatment. The article presents clinical features of SFT, the importance of surgical treatment and justification for using multidisciplinary approach, as well as a clinical case of treatment of recurrence involving tumor removal with resection of the femoral vessels and defect reconstruction with vascular implants.
