ENDOSCOPIC MUCOSAL RESECTION OF A GASTRIC METASTASIS FROM RENAL CELL CARCINOMA PRESENTING AS A POLYPOID TUMOR ; REPORT OF A CASE

Abstract

Metastasis of tumors to the stomach is quite uncommon. In particular, gastric wall metastasis from a renal cell carcinoma is extremely rare. This report presents a case of gastric wall metastasis from a renal cell carcinoma, treated with endoscopic mucosal resection. A 65-year-old male who had undergone left radical nephrectomy for renal cell carcinoma in October 2007, was referred for further evaluation of a gastric tumor in July 2009. Upper gastrointestinal endoscopy revealed a solitary polypoid lesion about 10 mm in diameter in the posterior wall of the middle gastric body. Endoscopic mucosal resection was performed as diagnostic therapy. Histopathological examination of the resected specimen confirmed a diagnosis of clear cell carcinoma, thus suggesting the presence of renal cell carcinoma metastasis.
