Renal cell carcinoma (RCC) accounts for 80-85% of all primary renal neoplasms. Although RCC can metastasize to any organ, gastric metastases from RCC are exceedingly rare. A 67-year-old male presented with melena and acute blood loss anemia. The patient had a history of RCC that had been treated with a radical nephrectomy. He had a recent myocardial infarction and was receiving double antiplatelet therapy. After hemodynamic stabilization, esophagogastroduodenoscopy showed a polypoid mass in the gastric fundus. The mass was excised. Histological and immunohistochemical evaluation were consistent with clear cell RCC. The polypoid lesion is consistent with a late solitary metastasis.
肾细胞癌（RCC）占所有原发性肾肿瘤的80-85%。尽管RCC可转移至任何器官，但RCC发生胃转移极为罕见。一名67岁男性因黑便和急性失血性贫血就诊。该患者有RCC病史，曾接受根治性肾切除术。他近期发生过心肌梗死，正在接受双联抗血小板治疗。血流动力学稳定后，食管胃十二指肠镜检查显示胃底有一息肉样肿物。该肿物被切除。组织学和免疫组化评估结果与透明细胞RCC一致。该息肉样病变符合晚期孤立性转移。
