URDIALES-VIEDMA, Mariano et al. Late thyroid and pancreas metastases from a clear cell renal carcinoma: Report of two cases. Arch. Esp. Urol. [online]. 2008, vol.61, n.6, pp.736-740. ISSN 0004-0614.

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: 1º) 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 pancreatic glands, the differential diagnosis must always include metastatic renal cell carcinoma. 4) The treatmet of choice is surgical resection.
