Solitary Fibrous Tumor of the Prostate: Case Report and Review of the Literature

Le résumé fourni par la source

Solitary fibrous tumor (SFT), typically found in the pleura, is exceptionally rare in the prostate. We present the case of a 54-year-old man with prostatic SFT, initially revealed as an abdominopelvic mass. Subsequent investigations shown a vascular tumor. The pathological examination found a 23-cm tumor originating from the prostate, composed of short spindle-shaped and polygonal cells with mild nuclear atypia. Occasional mitoses were observed, with vascular invasion. Immunohistochemically, the tumor cells strongly expressed CD34 and STAT6. The maximum Ki-67 labeling index for the tumor cells was 4%. This case report has highlighted one of the rare occurrences of solitary fibrous tumor. A comprehensive microscopic examination paired with an immunohistochemical analysis will be necessary to establish an accurate diagnosis.
