Background. Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare tumor and accounts for less than 0.5% of all primary lung neoplasms. Case. A 66-year-old woman complaining of a cough and fever was admitted to our hospital. Chest computed tomography (CT) revealed a lung tumor in the left lower lobe and swelling of the left hilar lymph node. CT also revealed consolidation with air bronchogram in the right middle lobe and left lingular segment. The patient was diagnosed with adenocarcinoma using a transbronchial lung biopsy (TBLB), and she underwent surgery for lung cancer (cT1bN1M0, stage IIA). We performed left lower lobectomy, lymphadenectomy, and resection of a lesion that was suspected to be bronchiectasis in the lingular segment. The tumor was diagnosed as acinar adenocarcinoma, pT1aN1M0, stage IIA, while the lesion in the lingular segment was pathologically diagnosed as MALT lymphoma. The patient was not diagnosed with MALT lymphoma following the analysis of a TBLB specimen from the lesion in the right middle lobe after surgery; she underwent a follow-up examination for this lesion. Conclusion. We experienced a case of pulmonary MALT lymphoma that was found after surgery for lung cancer.
