title: [Paraganglioma of the prostate: a case report and review of the literature].
abstract: OBJECTIVE
  To investigate the clinical presentation, pathologic features, treatment and prognosis of prostatic paraganglioma.
  
  
  METHODS
  We retrospectively studied a case of prostatic paraganglioma and reviewed relevant literature. The patient was a 39-year-old man, admitted for repeated hematospermia for over 12 months. After misdiagnosed as having prostate cancer, he underwent suprapubic prostatectomy, with the tumor completely removed.
  
  
  RESULTS
  Postoperative pathological examination confirmed the tumor to be prostatic paraganglioma, which was non-functional, with the immunohistochemical results of NSE (+), CGA (+), S100 (+), CK (-) and Desmin (-). Postoperative blood pressure was stable. Two weeks after surgery, the urethral catheter was removed and the patient discharged. No recurrence was found during 48 months of follow-up.
  
  
  CONCLUSIONS
  Lacking specific clinical characteristics, paraganglioma of the prostate is easily misdiagnosed, and can be confirmed only by postoperative pathology and immunohistochemistry. For the treatment of this rare tumor, little experience has been accumulated, and further studies are needed.
