We report two cases of renal cell carcinoma, primary lesions of which were not diagnosed at an early stage. The first case was a 58-year-old woman, who had nephrectomy due to staghorn calculus of left kidney. Fifteen months later, she died of metastatic cancer whose origin was unknown until the left kidney was re-examined. It was sarcomatoid renal cell carcinoma. The second case was 43-year-old woman, who had amputation of right index finger due to metastatic tumor. Renal cell carcinoma was highly suspected, but no tumor could be found in her kidneys although various urological examinations were performed. Two years later, abdominal CT scan showed a space-occupying lesion (SOL) of left kidney. She had left nephrectomy, and the origin was finally identified.
我们报告了两例肾细胞癌病例，其原发性病变在早期未被诊断出来。第一例是一名58岁女性，因左肾鹿角形结石接受了肾切除术。15个月后，她死于转移性癌症，在对左肾进行重新检查之前，其原发部位不明。结果是肉瘤样肾细胞癌。第二例是一名43岁女性，因转移性肿瘤接受了右手食指截肢术。高度怀疑是肾细胞癌，但尽管进行了各种泌尿外科检查，在她的肾脏中未发现肿瘤。两年后，腹部CT扫描显示左肾有一个占位性病变（SOL）。她接受了左肾切除术，最终确定了肿瘤的原发部位。
