We report a case of sarcomatoid renal cell carcinoma with chromophobe cell foci. The patient was a 57-year-old Japanese woman with a renal mass measuring 12x8x8 cm in diameter. Histologically, the tumor was composed predominantly of sarcomatoid renal cell carcinoma with foci of chromophobe cell carcinoma. The patient died of multiple metastases 2 months after operation. To the best of our knowledge, there have been only two reports of the coexistence of sarcomatoid renal cell carcinoma and chromophobe renal cell carcinoma in the literature. Our case indicates that chromophobe cell carcinoma may be connected with sarcomatoid renal cell carcinoma. In such a case, the prognosis may be related to the latter component.
我们报告一例伴有嫌色细胞灶的肉瘤样肾细胞癌。患者为一名57岁的日本女性，肾肿块直径为12×8×8厘米。组织学上，肿瘤主要由肉瘤样肾细胞癌和嫌色细胞癌灶组成。患者术后2个月死于多发转移。据我们所知，文献中仅有两篇关于肉瘤样肾细胞癌和嫌色性肾细胞癌共存的报道。我们的病例表明，嫌色细胞癌可能与肉瘤样肾细胞癌相关。在这种情况下，预后可能与后一种成分有关。
