Abstract

Introduction: Solitary fibrous tumor (SFT) is a rare mesenchymal tumor with an incidence of 2.8 per million inhabitants [2]. It was initially reported for its pleural location, which is the most frequent [3]. Abdominal, pelvic, and retroperitoneal tumors were also described, but retrovesical location is extremely rare, with only isolated cases reported.

Case Presentation: We report a case of a 23-year-old patient with retrovesical SFT with surgical attempt at another institution with favorable evolution after a complete oncological resection in our service. A review of diagnostic methods and differential diagnoses related to this pathology is made.

Discussion: SFTs are rare entities with a challenging manage. Most of them are benign, but they can become malignant with tendency to local recurrence and metastasize. Most patients are asymptomatic, but large tumors can cause compression symptoms of adjacent structures. By immunohistochemistry, they are reactive to CD34 and CD99. SFTs can also be positive for EMA, BCL2 and SMA.

Conclusion: Although the pleural location is the most frequent, it must be taken into account as a differential diagnosis of large pelvic masses of mesenchymal origin. Complete resection in a single block of these lesions is the accepted treatment.
