Key Words: Squamous cell carcinoma • Accessory cardiac bronchus
A 73-year-old man presented with mediastinal enlargement on a chest radiograph. Chest computed tomography (CT) scan revealed a 5x6-cm soft tissue mass in the azygoesophageal recess (Fig. 1) . Under diagnosis of squamous cell carcinoma the patient underwent right S6 segmentectomy, after induction chemotherapy. Preoperative examination using CT scanning, bronchoscopy, and macroscopic examination of the resected specimen indicated that the tumor arose from the distal parenchyma of an accessory cardiac bronchus (Fig. 2)

Fig. 1. (a) CT section at the level of the right main pulmonary artery on admission. The accessory cardiac bronchus can be identified (arrow), but the lumen is narrowed by the tumor. (b) CT section at the same level after chemotherapy. The tumor shrinkage was obtained. The lumen of the accessory cardiac bronchus is clearly demonstrated (arrow).
