Abstract

Low grade mucosa-associated lymphoid tissue (MALT) lymphoma is a very indolent disease and can achieve complete remission with only localized treatment unlike the low grade B-cell lymphoma originating from peripheral lymph nodes. The endoscopic finding of the low grade gastric MALT lymphoma is usually presented as multiple and superficial erosions or ulceration. We recently experienced one case of low grade gastric MALT lymphoma without any mucosal lesion. The patient was initially considered as a submucosal tumor originating from the proper muscle layer of stomach and underwent the subtotal gastrectomy. But the submucosal tumor was confirmed to the low grade gastric MALT lymphoma without H. pylori infection.
