The present case was of a 79-year-old man who underwent left nephrectomy for renal cell carcinoma (RCC) 14 years prior. Signs of anemia were observed, prompting an exploratory upper gastrointestinal endoscopy to search for the origin. The anemia was attributed to a hemorrhagic, tumorous lesion discovered in the fornix (size: ~30 mm). Endoscopic mucosal resection was performed to control the anemia. The patient was diagnosed with metastatic gastric cancer secondary to RCC, based on the abundance of clear-cell carcinoma cells in his pathological specimens, which resembled his surgical specimens taken 14 years prior. Late recurrence is not uncommon in RCC, and discoveries of gastric metastasis are often prompted by gastrointestinal bleeding. Such trends mean that clinicians should keep RCC in mind during a patient's examination and treatment if a hemorrhagic lesion (s) is observed in the stomach, even if a long time has passed since the diagnosis of RCC.
