Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal lymphoma arising in a number of epithelial tissues, including stomach, salivary gland and the lung. Pulmonary MALT lymphoma originates in the parenchyma and/or bronchi and is a rare disease, representing 0.5-1% of primary pulmonary malignancies. Although the time to diagnosis can be delayed because most patients are asymptomatic and investigations are usually driven by the accidental finding of abnormal lung imaging studies, it has an indolent course and a good prognosis. Here we report the case of an asymptomatic female patient with a nodular lung opacity that was found to persist five months after an episode of community-acquired pneumonia. A final diagnosis of pulmonary MALT lymphoma was obtained after an extensive diagnostic work-up.
