A low grade, indolent B-cell lymphoma, usually associated with Helicobacter pylori infection. Morphologically it is characterised by a dense mucosal atypical lymphocytic (centrocyte-like cell) infiltrate with often prominent lymphoepithelial lesions and plasmacytic differentiation. Some of gastric MALT lymphomas carry the t(11;18)(q21;q21). Such cases are resistant to Helicobacter pylori therapy.
