A 56-year-old man was coincidentally found to have a nodule in S1 of the right lung on chest computed tomography. On bronchoscopy, a smooth-surfaced polypoid lesion was identified at the orifice of the right B3b. Histopathological findings of transbronchial lung biopsy (TBLB) from right B1b indicated adenocarcinoma, and biopsy of the polypoid tumor indicated myxoma. A right upper lobectomy was therefore performed. Postoperatively, we diagnosed adenocarcinoma of the lung (pathological T2aN1M0, Stage IIA), and the patient received adjuvant chemotherapy. Myxoma is relatively uncommon and usually occurs in muscle or juxta-articularly. Endobronchial myxoma is exceptionally rare. To the best of our knowledge, this represents the first report of primary endobronchial myxoma accompanying adenocarcinoma of the lung.
