Introduction: Solitary fibrous tumors (SFTs) of the prostate are extremely rare. We report on a 60-year-old man who was diagnosed with prostatic SFT through transurethral resection (TUR) of the prostate, and we provide a narrative literature review to put the case into perspective. We looked into multiple databases for articles published before June 2022. Case Report: A 60-year-old man without comorbidities presented with acute urinary retention and significant macrohematuria. Due to recurrent bladder tamponades and relevant blood loss despite irrigation, an emergency endoscopic transurethral evaluation was initiated. Intraoperatively, diffuse venous hemorrhage from prostatic vessels around the bladder neck was detected, as well as significant hemorrhage from a grossly enlarged and tumor-suspicious prostate middle lobe. Within the framework of extensive bipolar coagulation, parts of the suspicious middle lobe were removed via TUR. The final histopathology report showed incompletely resected SFT of the prostate. Due to the extremely rare SFT diagnosis, the case was discussed in an interdisciplinary tumor board and further diagnostic workup, including thoracoabdominal computed tomography and magnetic resonance imaging of the pelvis, was performed, which revealed no secondary tumors or signs of metastasis. According to the tumor board recommendation, robot-assisted radical prostatectomy (RARP) with bilateral nerve sparing was performed, supported by intraoperative frozen section. The final histopathology confirmed the SFT that had developed from the transition zone. The SFT was resected with negative frozen section result and negative surgical margins (R0). No intra- and perioperative complications occurred, and in the short-term follow-up, the patient presented in excellent general status with full continence. From 1997 to June 2022, we identified a total of 12 publications reporting on treatment for prostatic SFT (11 case reports and 2 patient series), with none performing bilateral nerve sparing, frozen section, or robot-assisted radical prostatectomy. No common survival endpoints were accessible. Conclusion: This case demonstrates the exceedingly rare case of SFT of the prostate, which has been described in the literature in only 23 men worldwide. Here, we were the first to demonstrate the feasibility of bilateral nerve-sparing RARP supported by frozen section. A systematic review was not possible due to the lack of common endpoints.
