Solitary fibrous tumour of the prostate identified on needle biopsy.

The clinical and radical prostatectomy features of a case of solitary fibrous tumour (SFT) of the prostate identified on needle biopsy are presented. The main differential diagnoses are discussed. SFTs involving the prostate are relatively uncommon, with only isolated cases reported in the literature. Owing to their relative rarity and lack of long-term follow-up, the clinical behaviour of prostatic SFTs is difficult to predict. Complete resection of the tumour is currently the single main prognostic factor.
