title: Cystosarcoma phyllodes of the seminal vesicle.
abstract: BACKGROUND
  We report here an extremely rare case of cystosarcoma phyllodes of the seminal vesicle.
  
  
  METHODS
  A 65-year-old man presented with urinary hesitancy, frequency and constipation. Clinical examinations including two needle biopsies were performed, and the patient had undergone open surgery.
  
  
  RESULTS
  The final pathological diagnosis was cystosarcoma phyllodes of the seminal vesicle. Seven months after the operation, a chest X-ray showed lung metastasis, and the patient died 11 months after the operation.
  
  
  CONCLUSIONS
  To our knowledge, only one case of cystosarcoma phyllodes of the seminal vesicle has been previously reported.
