A Rare Case of Solitary Fibrous Tumor of Prostate – A Case Report
- Solitary fibrous tumor (SFT), initially thought to be limited to the pleura can now be seen in numerous other sites. Prostatic solitary fibrous tumor is exceedingly rare and presents with nonspecific symptoms. We report a case of solitary fibrous tumor in a 43-year-old male patient who presented with obstructive urinary symptoms. A Trans rectal ultrasonography guided prostate biopsy was done. Microscopic examination revealed a lesion composed of spindle cell arranged in storiform pattern admixed with bands of collagen and haemangiopericytomatous vessels. Immunohistochemically the spindle cells stained positive for CD34 and STAT6 thus confirming the diagnosis of SFT. The patient underwent complete resection and the recovery was uneventful. Currently complete excision seems to be the most important prognostic factor. We also review the histologic mimics of SFT and the utility of STAT6 in aiding the diagnosis of SFT.
