Renal cell carcinoma (RCC) is a common malignant kidney tumor; however, gastric metastasis is rare. We report the case of an 82-year-old male patient who developed gastric metastasis 12 years after an initial diagnosis of RCC. The patient underwent endoscopic full-thickness resection (EFTR), and the gastric metastatic focus was successfully removed. Postoperative pathology and immunohistochemistry showed that the gastric metastasis originated from RCC. Although gastric metastasis of RCC is rare, it should be suspected in patients with a history of RCC or gastrointestinal symptoms. EFTR is associated with reduced trauma and greater retention of gastric tissue and function. It is a more appropriate choice than surgical resection; however, it requires more endoscopists.
肾细胞癌（RCC）是一种常见的肾脏恶性肿瘤；然而，胃转移很少见。我们报告一例82岁男性患者，在初次诊断为RCC 12年后发生胃转移。该患者接受了内镜全层切除术（EFTR），胃转移灶被成功切除。术后病理及免疫组化显示胃转移灶起源于RCC。虽然RCC的胃转移很少见，但有RCC病史或出现胃肠道症状的患者应怀疑有胃转移。EFTR具有创伤小、能更好地保留胃组织和功能的特点。它比手术切除是更合适的选择；然而，它需要更多的内镜医师。
