Metastasis of renal clear cell carcinoma (RCC) to the breast is exceptional. Breast metastases of extra-mammary tumors are rare and usually involve melanoma, lymphoma or leukemia. We report the case of a patient with breast metastasis of renal clear cell carcinoma occurring 18 years after nephrectomy. A history of RCC should always raise suspicion about breast metastasis, a situation that remains exceptional and whose diagnosis relies on anatomopathology.
肾透明细胞癌（RCC）转移至乳腺极为罕见。乳腺外肿瘤转移至乳腺的情况罕见，通常涉及黑色素瘤、淋巴瘤或白血病。我们报告一例肾透明细胞癌乳腺转移患者，该转移发生在肾切除术后18年。有RCC病史时应始终怀疑乳腺转移，这种情况仍然罕见，其诊断依赖于解剖病理学。
