There have been some reports describing metastasis to the stomach from renal cell carcinomas. However, there are few reports describing solitary synchronous gastric metastasis of renal cell carcinomas.
The patient was a 70-year-old woman who underwent an upper gastrointestinal endoscopy to examine her progressive weight loss. There was a submucosal tumor in the stomach, which was biopsied. The gastric tumor was pathologically proven to be a metastatic clear cell renal cell carcinoma. Furthermore, contrast-enhanced computed tomography showed right renal cell carcinoma invading the renal vein (cT3aN0M0). The patient underwent right radical nephrectomy and endoscopic resection for the treatment of the primary renal cancer and the gastric metastatic lesion, respectively. The resected specimen of the stomach had a clear resection margin.
Endoscopic resection for early stage gastric metastatic lesions of renal cell carcinomas is a reasonable approach because it is a minimally invasive surgical technique.
已有一些关于肾细胞癌转移至胃的报道。然而，描述肾细胞癌孤立性同步胃转移的报道较少。
该患者为一名70岁女性，因体重逐渐减轻接受了上消化道内镜检查。胃内有一个黏膜下肿瘤，进行了活检。胃肿瘤经病理证实为转移性透明细胞肾细胞癌。此外，增强计算机断层扫描显示右肾细胞癌侵犯肾静脉（cT3aN0M0）。患者分别接受了右根治性肾切除术和内镜切除术，以治疗原发性肾癌和胃转移灶。切除的胃标本切缘清晰。
对于肾细胞癌早期胃转移灶，内镜切除术是一种合理的方法，因为它是一种微创手术技术。
