title: Renal and retroperitoneal metastasis from prostate adenocarcinoma: a case report.
abstract: BACKGROUND
  Diffuse renal and retroperitoneal metastasis of prostatic origin is an uncommon spread pattern of prostate cancer.
  
  
  METHODS
  We described a 74-year-old male patient who was admitted because of dysuria and nocturia. Physical examination and imaging study indicated prostate mass, and laboratory analysis revealed elevated prostate specific antigen (PSA). The diagnosis of prostate cancer was established after biopsy. In the further evaluation, diffuse renal and retroperitoneal metastasis of prostate cancer was confirmed. Radiotherapy combined with endocrine therapy was given.
  
  
  CONCLUSIONS
  Our present case emphasized that the routine metastatic work-up was quite necessary, since a small proportion of men with advanced prostate cancer might experience metastases in atypical sites.
