A 62-year-old woman was admitted with a 20 mm diameter tumor in the left upper lobe of the lung. Preoperative computed tomography (CT) revealed a displaced anomalous B1+2 arising from the left main bronchus. In addition, an accessory fissure was detected between the apicoposterior (S1+2) and anterior (S3 ) segments. As the lesion was entirely contained in the S1+2, we performed video-assisted thoracic surgical S 1+2 segmentectomy with systematic lymph node dissection. During the operation, we easily detected and successfully divided the displaced B1+2 located behind the left main pulmonary artery. The pathological diagnosis was invasive adenocarcinoma with T1bN0M0 (TNM 8th edition). Histologically, neither lymphatic invasion nor vascular invasion was detected in the invasive area of the tumor. If regional lymph node dissection with appropriate intraoperative histologic examination by frozen section could be made, segmentectomy may be an acceptable, optional procedure with curative intent for cancer patients with such an anomaly.
