 A 60-year-old man underwent EGD(esophagogastroduodenoscopy)6 years ago. A 10mm submucosal tumor was found in the gastric body. The lesion increased in size ; therefore, he was referred to our hospital. EGD revealed a broad-based protruded submucosal tumor, 30mm in size, covered with normal gastric mucosa. Endoscopic ultrasonography revealed the tumor to be a hypoechoic mass located mainly in the third layer of the gastric wall. A small anechoic area was also observed. We suspected heterotopic pancreas of the stomach, and ESD(endoscopic submucosal dissection)was performed for definitive diagnosis. Histologically, small and uniform lymphocytes were diffusely proliferated with lymphoid follicles between the mucosal layer and the muscularis propria of the gastric wall. We finally diagnosed a gastric marginal zone lymphoma of mucosa-associated lymphoid tissue, and the clinical stage was identified as Stage I(Lugano International Classification). He did not develop any recurrence 3 years after the ESD.
