Abstract:
The rate of bronchial anomaly is reported to be about 0.6%.Most of cases showed a displaced bronchus, mostly in the right upper lobe. We experienced lung cancer in a displaced anomalous lingular bronchus. A 76-year-old male was referred to our hospital due to abnormal mass on a chest radiograph. Thoracic computed tomography( CT) revealed a tumor with a maximum diameter of 42 mm in the left lingular segment. Bronchoscopic examination indicated a displaced anomalous right upper bronchus branching from the trachea and left B4+5 branching from the stem of the left lower lobe bronchus. Curetting was performed through the left B4+5, and adenocarcinoma was diagnosed. Lobulation between the upper and lingular segments was noted during surgery, and left lingular segmentectomy was performed. The tumor was histologically diagnosed as adenocarcinoma. The postoperative course was uneventful.
