Approximately 85% of kidney tumors are renal cell carcinoma (RCC). RCC commonly metastasizes to the lung, bone, and lymph nodes; however, gastric metastasis is exceedingly rare. We present an 86-year-old woman with left-sided RCC with known metastatic disease to the lungs, lymph nodes, and bone, who presented with acute blood loss anemia. After hemodynamic stabilization, esophagogastroduodenoscopy revealed a large infiltrative, polypoid, and ulcerated polyp in the gastric body. After complete polypectomy, histological examination demonstrated gastric mucosa ulcerated by clear-cell carcinoma, compatible with metastatic RCC. Our patient was successfully treated with palliative radiation to the gastric body.
大约85%的肾肿瘤是肾细胞癌（RCC）。肾细胞癌通常会转移至肺、骨和淋巴结；然而，胃转移极为罕见。我们报告一名86岁女性，患有左侧肾细胞癌，已知已转移至肺、淋巴结和骨，她因急性失血性贫血就诊。在血流动力学稳定后，食管胃十二指肠镜检查发现胃体有一个大的浸润性、息肉样且溃疡的息肉。完整切除息肉后，组织学检查显示胃黏膜被透明细胞癌溃疡，符合转移性肾细胞癌。我们的患者接受了胃体姑息性放疗，治疗成功。
