Extranodal marginal zone B-cell lymphoma, also known as mucosa-associated lymphoid tissue (MALT) lymphoma: This is the most common type of marginal zone lymphoma. It starts in places other than the lymph nodes (extranodal). Most MALT lymphomas start in the stomach and are linked to infection by Helicobacter pylori (the bacteria that causes many stomach ulcers). MALT lymphoma might also start in the lung, skin, thyroid, salivary glands, or tissues surrounding the eye. Usually the lymphoma stays in the area where it begins and is not widespread. Many of these other MALT lymphomas have also been linked to infections with bacteria or viruses.
