Abstract

Increasing numbers of extrapleural solitary fibrous tumours (SFTs), including the prostate SFT, have been reported over the last 10‑years. Prostate SFT is relatively uncommon, with <20 cases reported in the literature worldwide. In the present study, a prostate SFT case, which was initially misdiagnosed as benign prostatic hyperplasia, is presented. The patient was subjected to three surgeries (cystoscopy and per urethra lithocystotomy, transurethral resection of the prostate and nerve‑sparing retropubic radical prostatectomy) prior to SFT diagnosis. It was demonstrated that histopathological and immunohistochemical factors (positive staining for CD34 and B cell lyphoma‑2 expression) were of significant diagnostic value. Thus, nerve‑sparing retropubic radical prostatectomy for total resection may be the best therapeutic strategy to treat prostate SFT, allowing the preservation of sexual function and reducing the risk of locoregional recurrence.
