A Strange Dweller in Pulmonary Mass: Lung MALToma: Case Report

MALT (mucosa-associated lymphoid tissue) lymphoma is an extranodal marginal zone B-cell lymphoma. Although the most common site of MALT lymphoma is gastrointestinal tract; salivary glands, orbit, lung, skin, thyroid, breast, liver, kidney, bladder, prostate have been reported. Lung MALToma (LM) or more correctly BALT (bronchus-associated lymphoid tissue) lymphoma springs in the marginal zone and marauds the bronchial epithelium by cellular lymphocytic infiltration. Lesions in lungs smaller than generally 3 cm in size are accepted as solitary pulmonary nodule. If they exceed this dimension, they are called pulmonary masses. Lots of benign and malign pulmonary or extrapulmonary pathologies lodge in these lesions. Lymphomas are rarely seen in these masses. Here, we report a MALT lymphoma of the lung.
