Abstrakt:	Objective: To describe the clinical and histological findings of a case of renal cell carcinoma metastatic to the testes, an uncommon site of metastasis of this tumor type that can cause difficulty in making the differential diagnosis and consequently, in the staging and treatment of the disease. Methods/results: A 65-year-old patient diagnosed of renal cell carcinoma presented a paratesticular mass. Histopathological examination of the orchidectomy specimen showed proliferation of clear cells arranged in a diffuse pattern, with intimate intertwining with vascular structures. Tumor cells were strongly positive for vimentin, CAM5.2 and EMA. Conclusions: Although renal cell carcinoma rarely metastasizes to the testes, it should be considered in the differential diagnosis of testicular masses. Histological examination is essential to diagnosis and correct management.
