018. BALT lymphoma: a 15-year retrospective study—difficulties in diagnosis-identification

Abstract

Background BALT lymphoma represents a low-grade B-cell lymphoma, derived from cells of the marginal zone of the bronchus-associated lymphoid tissue (WHO 2004). It accounts for less than 0.5% of all lung neoplasms, but constitutes 70-90% of all lung lymphomas. The majority of patients are in their fifth-seventh decade of life. Pulmonary lesions are frequently discovered incidentally on a routine chest radiograph as solitary nodule or less common as multiple unilateral or bilateral nodules or diffuse lobar infiltrates.
