title: Extranodal marginal zone lymphoma of MALT involving the lungs, the stomach, and the colon.
abstract: Extranodal marginal zone lymphoma of MALT, previously known as MALT lymphoma, is a low grade B-cell Non-Hodgkin's lymphoma (NHL). Its most frequent locations are the gastrointestinal tract and the lungs while that of the colon is rare. Involvement of multiple mucosal sites is not a frequent finding but it does occur. We describe a case of a 70-year-old man who presented with extranodal marginal zone lymphoma of MALT involving three different sites: the lungs, the stomach, and the colon.
