A 43-year-old woman had cryesthesia of the fingers and cyanosis, and an antinuclear antibody had been positive for 8 years. She was admitted to our hospital because of dyspnea on exertion and wheezing from 1 month previously. Chest computed tomography showed multiple cysts in both lungs, reticular shadows in the bilateral lower lobes, and a tumor in the left main bronchus. A bronchoscopic examination showed a submucosal tumor, with a smooth surface and proliferation of blood vessels. A biopsy of the tumor was performed, and mucosa-associated lymphoid tissue (MALT) lymphoma was diagnosed. Video-assisted thoracoscopic surgery was performed to obtain a complete resection, and the pathological diagnosis was the same. The patient was also diagnosed with Sjögren's syndrome. Bronchial MALT lymphoma is extremely rare, and it is important to consider bronchial tumors in patients presenting with wheezing.
