Abstract：
This is a case report about a patient which presents with two right renal tumors, one of them being an oncocytoma with typical histopathological features and renal vein extension. Recent studies show that despite renal vein thrombus being a histological sign of malignancy; when associated with renal oncocytoma, it should not alter the benign prognosis of oncocytoma, and a simple follow-up may be carried. Further explorations should be done when easily available, and when the histopathologic diagnosis of oncocytoma is uncertain, to rule out the differential diagnosis of a chromophobe renal cell carcinoma, oncocytic variant.

这是一例关于患者出现两个右肾肿瘤的病例报告，其中之一是具有典型组织病理学特征和肾静脉延伸的嗜酸细胞瘤。最近的研究表明，尽管肾静脉血栓是恶性肿瘤的组织学标志；当与肾嗜酸细胞瘤相关时，它不应该改变嗜酸细胞瘤的良性预后，可以进行简单的后续行动。如果容易获得，应进行进一步的探索，当嗜酸细胞瘤的组织病理学诊断不确定时，为了排除肾嫌色细胞癌的鉴别诊断，嗜酸性细胞变异体。
