Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma is a common low grade B-cell lymphoma arising from a background of chronic inflammatory disease at a number of mucosal sites.The association between Helicobacter pylori and gastric MALT lymphoma is well known and it appears that H. pylori is critical for lymphomagenesis and also creates a microenvironment favoring the growth of neoplastic B cells.The understanding of MALT lymphoma biology has significantly improved, and at least 4 recurrent translocations t(11;18)/ API2-MALT1, t(1;14)/IGH-BCL10, t(14;18)/IGH-MALT1 and t(3;14)/IGH-FOXP1 have been implicated in the pathogenesis of MALT lymphoma.Here, we review the recent advances in association of microorganisms with MALT lymphoma and the molecular genetics underlying the lymphoma development.(Korean
