Renal cell carcinoma (RCC), a highly aggressive malignant tumor, exhibits a significant propensity for metastasis. Common metastatic sites include the lung, bone, liver, and brain. This report presents a case of gastric metastasis originating from renal cell carcinoma in a 62-year-old male patient who was diagnosed with clear cell renal cell carcinoma in the left kidney in March 2024. The gastric space-occupying lesion was confirmed through imaging studies, gastroscopy, and histopathological examination. This case is documented herein to enhance clinical awareness and improve diagnostic accuracy for this rare manifestation of RCC.<\/jats:p>","DOI":"10.3389\/fonc.2025.1624528","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T04:10:32Z","timestamp":1755490232000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Gastric
