Gastric MALT lymphoma usually presents with various endoscopic morphologic characteristics. The majority of the endoscopic findings of low-grade gastric MALT lymphoma reveal multiple and superficial erosions or ulceration with mucosal nodularity, but high-grade gastric MALT lymphomas show ulceroinfiltrative and fungating lesion. However, low-grade gastric MALT lymphoma that presents as advanced gastric cancer is very rare. We experienced a case of low-grade gastric MALT lymphoma with perigastric lymph node infiltration; it presented as advanced gastric cancer, and it was treated with H. pylori eradication and CHOP chemotherapy. So we report on this case along with a review of related literatures. (Korean J Gastrointest Endosc 2005;31:323327)
