 We used magnifying endoscopy for not only gastric cancer but also gastric MALT lymphoma and gastritis with Helicobacter pylori infection.

 Although endoscopic appearances of MALT lymphoma are various, nonstructural areas without gastric glands and abnormal vessels with irregularity are characteristics in magnified endoscopic images. Magnified endoscopic findings reflect pathological views such as infiltration of lymphoma cells and destruction of gastric epithelium, and they change to similar surface microstructure in the background after eradication of lymphoma. Biopsy of the nonstructural area is useful to decrease sampling errors, to target biopsy for diagnosis and for evaluation after treatment.
