PACHON SANCHEZ, Diego et al. Carcinoma de celulas renales asociado a oncocitoma renal contralateral metacrónico. Arch. Esp. Urol. [online]. 2005, vol.58, n.2, pp.175-178. ISSN 0004-0614.

OBJECTIVES: To report one case of renal cell carcinoma and contralateral metacronous oncocytoma, and to perform a bibliographic review on the topic. METHODS: 52-year-old male patient with history of right radical nephrectomy for renal cell carcinoma. On his ten-year follow-up multiple lesions appeared in the left kidney. Partial nephrectomy was performed. Pathological study showed three oncocytomas. CONCLUSIONS: The presence of metacronous lesions in the contralateral kidney of a patient with history of renal cell carcinoma is rare. The presence of the same histological type of tumor should always be suspected and the management should follow this suspicion. Contralateral metacronous oncocytoma is a rare pathology which has not been reported in the literature so far.
