Gastric metastasis from renal cell carcinoma (RCC) is a very rare event and treatment for such patients has not been established. We report two cases of gastric metastasis from RCC. The first case was in a 67- year-old man with a past history of right radical nephrectomy for RCC (ypT3aN0M0) six years ago. The whole-body computed tomography (CT) revealed multiple lung nodules. We performed gastrointestinal endoscopy to find the primary lesion, and detected multiple submucosal tumors in the gastric body. Needle biopsy of these tumors revealed gastric metastasis from RCC. Oral sorafenib tosylate therapy was started. Twenty months later, gastrointestinal endoscopy showed only gastric erosion without malignant evidence. The second case was in a 70-year-old man complaining of epigastralgia. He had undergone right partial nephrectomy for RCC (pT1aN0M0) six years ago, and thoracoscopic wedge resection of a solitary lung nodule one year ago. Gastrointestinal endoscopy detected a solitary hyperplastic polyp in the anterior wall of the gastric body. Needle biopsy of this polyp revealed gastric metastasis from RCC. We performed laparoscopic partial gastrectomy. Gastrointestinal endoscopy and CT showed no evidence of metastasis or recurrence for 14 months after gastrectomy.
