title: [Metastatic testicular carcinoma].
abstract: OBJECTIVE
  To describe 11 cases of metastatic carcinoma of the testicular parenchyma presenting as a scrotal mass.
  
  
  METHODS
  A descriptive and retrospective study of metastatic carcinoma of the testis was performed. Eleven cases of testicular metastasis from prostate cancer (7), renal adenocarcinoma (2), bladder carcinoma (1) and carcinoma of the pancreas (1) are presented.
  
  
  RESULTS
  All the patients had multiple disseminated disease from their underlying condition, which is a sign of poor prognosis.
  
  
  CONCLUSIONS
  Testicular metastasis from carcinoma is rare and frequently arises from adenocarcinoma of the prostate. Clinically, testicular metastases cannot be distinguished from primary tumors and generally affect males over 60 years old.
