Chromophobe renal cell carcinoma (RCC), which has recently been recognized to be a distinct type of RCC, comprises approximately 5% of renal cell tumors. It has been hypothesized that the cells that comprise chromophobe RCC show a phenotype similar to that of intercalated cells of the collecting duct. Although the number of research reports on this type of tumor has recently been increasing, only nine cases of chromophobe RCC showing sarcomatoid transformation have been described. Herein, a case of chromophobe RCC with sarcomatoid foci and a small daughter lesion is reported.
嫌色性肾细胞癌（RCC）是最近才被认定的一种独特类型的肾细胞癌，约占肾细胞肿瘤的5%。据推测，构成嫌色性肾细胞癌的细胞表现出与集合管闰细胞相似的表型。尽管最近关于这类肿瘤的研究报告数量不断增加，但仅有9例显示肉瘤样转化的嫌色性肾细胞癌被描述。在此，报告1例具有肉瘤样病灶和一个小的子病灶的嫌色性肾细胞癌病例。
