title: [Late thyroid and pancreas metastases from a clear cell renal carcinoma. Report of two cases].
abstract: OBJECTIVE
  To report two cases of late metastases of clear cell renal cell carcinoma.
  
  
  METHODS
  Two patients, a male and a female with history of nephrectomy 17 and 16 years before for renal cell carcinomas, presented new tumours in the thyroid and pancreas, which were excised.
  
  
  RESULTS
  Pathology reported that both lesions were clear cell tumours and immunohistochemically they were consistent with metastases from clear renal cell carcinomas.
  
  
  CONCLUSIONS
  1) Previous history of any type of carcinoma should suggest the possibility of metastases when facing a thyroid or pancreatic nodule. 2) All-life follow-up should be made, nephrectomy (resection) for a renal cell carcinoma. 3) In the presence of a clear cell tumour of the thyroid or pan-creatic glands, the differential diagnosis must always include metastatic renal cell carcinoma. 4) The treatment of choice is surgical resection.
