NCIt definition : An extranodal marginal zone lymphoma that arises from the lung. It is characterized
by the neoplastic proliferation of small B-lymphocytes, monocytoid cells and cells
with plasma cell differentiation in the marginal zones of reactive lymphoid follicles.
The neoplastic cells infiltrate the interfollicular areas and the bronchial epithelium
forming lymphoepithelial lesions. The neoplasm is usually discovered as a mass in
a chest x-ray in asymptomatic patients. When symptoms occur, they include cough, dyspnea,
hemoptysis, and chest pain. If the lung lesions are resectable, surgery can result
in prolonged remission.;
