Abstract

Chromophobe renal cell carcinomas (ChRCCs) have a good prognosis and comprise approximately 5-7% of renal cell carcinomas (RCCs). The sarcomatoid differentiation in RCC is found in around 5-10% of cases; however, in ChRCC, it is much less than in other RCCs and poorly responds to chemotherapeutic agents. A study by de Peralta-Venturina et al. found 9% sarcomatoid differentiation in chromophobe RCC. We present the case of a 58-year-old female with a left abdominal mass diagnosed as ChRCC with the existence of sarcomatous differentiation including osteosarcomatous and chondrosarcomatous, which are of adverse prognosis. Osteosarcoma-like divergent differentiation in RCC is extremely rare, with limited documented cases. It should be carefully considered in evaluating and managing renal masses due to its potential impact on clinical outcomes.

伴肉瘤样分化(骨肉瘤样和软骨肉瘤样分化)的Chromophobe肾细胞癌--病例报告和全面综述。
嗜铬细胞肾细胞癌(Chromophobe renal cell carcinomas,ChRCC)预后良好,约占肾细胞癌(RCC)的 5-7%。RCC中肉瘤样分化的病例约占5%-10%;然而,ChRCC的肉瘤样分化程度远低于其他RCC,而且对化疗药物的反应较差。de Peralta-Venturina 等人的研究发现,嗜色性 RCC 中肉瘤样分化率为 9%。我们介绍了一例 58 岁女性的病例,她的左腹部肿块被诊断为 ChRCC,存在肉瘤样分化,包括骨肉瘤样和软骨肉瘤样,预后不良。骨肉瘤样分化在 RCC 中极为罕见,记录在案的病例有限。由于其对临床结果的潜在影响,在评估和管理肾肿块时应谨慎考虑。
