Abstract
- A solitary fibrous tumor (SFT) is now commonly accepted to derive from mesenchymal cells differentiating toward fibroblast or myofibroblast. Although the extrapleural manifestations of SFT have been documented in almost all sites, an SFT arising in the genitourinary tract is extremely rare, with less than 10 cases having been reported. The histopathological criteria between a benign and a malignant SFT are obscure, and their biological behaviors remain controversial. The choice of treatment of an SFT remains to be clarifies. Herein, a case of a bladder SFT, well encased within the submucosa and bladder muscle, is reported. The SFT of bladder was completely excised, and there was no evidence of recurrence after 15 months of follow-up.
