title: [Metachronic testicular metastasis secondary to clear cell renal adenocarcinoma].
abstract: OBJECTIVE
  To report one case of unusual testicular metastasis from a renal origin.
  
  
  METHODS
  57 year-old patient with disseminated right renal cancer under treatment who presented bone metastasis and a painful nodule in the upper pole of the right testicle during his follow-up with medical therapy, making surgery necessary. The pathology result was clear cell adenocarcinoma.
  
  
  RESULTS
  Six months later the patient continues under oral Sorafenib without evidence of new metastatic implants.
  
  
  CONCLUSIONS
  Testicular secondary metastatic tumors account for less than 1% of old testicular tumors. In patients in the fifth and sixth decades, mainly if they are affected by other neoplasias, testicular masses use to be metastatic implants. The most frequent origin is prostate.
