[Solitary fibrous tumor of the prostate: case report].

Solitary fibrous tumour is usually a benign and rare mesenchymal tumour. The first case was reported in patients with pleural involvement. Solitary fibrous tumour of the prostate is exceptional. We here report the case of a 77-year-old patient presenting with lower urinary tract symptoms such as dysuria and polalkiuria. CT scan and MRI showed the prostate lesion and determined its relation to adjacent healthy structures, an important factor in evaluating tumour resectability. Transrectal biopsy with immunohistochemical examination confirmed the diagnosis; CD34, Bcl2 and CD 99 were expressed. Radical prostatectomy was performed.
