• gastric follicular lymphoma
• endoscopic submucosal dissection

We herein report the case of 74-year-old man with gastric follicular lymphoma resected by endoscopic submucosal dissection (ESD). A submucosal tumor 7 mm in diameter was detected at the gastric middle body. Endoscopic ultrasonography showed a homogenous hypoechoic tumor localized in the submucosa. The tumor was removed by ESD immediately, before further tumor growth would preclude endoscopic resection. The pathological findings indicated follicular lymphoma (FL) with negative horizontal and vertical margins. The clinical stage of FL was confirmed to be stage I by extensive work-up procedures, including contrast-enhanced computed tomography, fluorodeoxyglucose-positron emission tomography. esophagogastroduodenoscopy, and colonoscopy. The patient remains in complete remission without any treatment.
