Abstract
We report two cases of AGML after initial H. pylori infection. Both cases were diagnosed as initial infection because endoscopic finding of the body showed regular arrangement of collecting venules (RAC). Case 1. A 32-year-old man who suffered from severe epigastralgia after endoscopic examination at the other hospital visited at our hospital. Since endoscopic examination at our hospital showed AGML and RAC on the body, he was diagnosed as AGML after initial H. pylori infection. The culture of biopsy specimen revealed H. pylori infection and serological examination showed that anti-H. pylori-antibody was negative. After two month, anti-H. pyloriantibody changed to positive. Case 2. A 27-year-old woman who suffered from severe nausea and epigastralgia visited to our hospital. Since endoscopic examination at our hospital showed AGML and RAC of the gastric body, she was diagnosed as AGML after initial H. pylori infection. Especially, as she was taken endoscopic examination by magnifying endoscopy, collecting venules were observed in detail. The origin of infection of the second case was unknown. In conclusion, RAC was very practical for diagnosing initial H. pylori infection cases.
