marginal zone lymphoma

a heterogeneous group of neoplasms originating from the B-cell-rich zones of the lymph nodes, spleen, or extranodal lymphoid tissue. Those tumors originating from mucosa-associated lymphoid tissue (MALT), most often in the stomach, intestines, salivary glands, and lungs, are called MALTomas.
