Solitary Fibrous Tumor of the Pelvis: A Case Report and Literature Review

Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm, occasionally arising in the retroperitoneal or pelvic cavities. Periprostatic SFTs are especially uncommon and can mimic primary prostatic neoplasms. While often benign, they may behave unpredictably. We report a case of a 76-year-old male with a large periprostatic SFT managed surgically, and we review the literature. Histopathological and immunohistochemical features confirmed the diagnosis, and risk stratification classified the tumor as intermediate risk. This case underscores the importance of accurate diagnosis, complete surgical resection, and long-term follow-up due to potential recurrence.
