Abstract
-
Low grade MALT lymphoma of stomach is associated with H. pylori infection in more than 90% of cases, and eradication of H. pylori leads to regression of the low grade MALT lymphoma in 60~90% of cases. On the contrary, high grade MALT lymphoma is thought to be independent from H. pylori for growth and usually is thought to require antitumor chemotherapy. However, there have been recent reports of high grade MALT lymphoma regressing after H. pylori eradication. We experienced and are reporting a case of high grade MALT lymphoma arising in the background of low grade MALT lymphoma that showed complete regression after H. pylori eradication.
