Case Report: Two cases of primary pulmonary endobronchial extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue localized in the trachea and bronchus

This study highlights the importance of considering endobronchial MALT lymphoma as a potential diagnosis. A thorough bronchoscopic evaluation of the central airways, along with appropriate biopsy of suspicious lesions, is crucial. Endobronchial MALT lymphoma should be suspected when targeting multiple widely stalked and smooth submucosal nodules or protrusions, mainly located in the central airways.
