Indolent B-cell lymphomas that are supposed to derive from the marginal zone (marginal zone lymphomas) include three specific entities: extranodal marginal zone lymphoma or mucosa-associated lymphatic tissue (MALT) lymphoma, splenic marginal zone lymphomas (SMZLs), and nodal marginal zone lymphomas (NMZLs).
