  • Abstract
  • Look Inside

 A female, at the age of 62, underwent mass screening of the upper gastrointestinal tract and was noticed to have both convergency and interruption of folds and an irregularly-shaped depression with internal granules on the anterior wall of the angular part. She was followed up subsequently by detailed examination because of suspicion of poorly-differentiated cancer. Endoscopy and x-ray showed that the lesion was characterized by narrow ditch-shaped erosions accompanied by whitish coating and roundish evenly sized granules surrounded by the ditch-shaped erosions. This was clinically diagnosed as MALT (mucosa-associated lymphoid tissue) lymphoma. Biopsy diagnosis was also compatible with MALT lymphoma. Furthermore, gene reconstruction at the site of Ig (H) JH was present. Based on the above alterations, the lesion was finally diagnosed as MALT lymphoma of the stomach and eradication therapy against H. pylori was carried out. Endoscopic findings have improved, biopsy findings indicative of MALT lymphoma have disappeared, and observation is still being carried on now. In the differential diagnosis of superficial-type malignant lymphoma of the stomach, a variety of diseases can be specified from atrophic gastritis to advanced gastric cancer. Generally, clinical diagnoses at the initial examination vary (about 50%), between type-Ⅱc, multiple erosion/ulcer, atrophic gastritis, etc., so, in clinical practice, the possibility of the presence of MALT lymphoma should also be kept in mind.
