Surgical Resection for Rare Cases of Lung Cancer in Teenagers

We experienced two cases of lung cancer in teenagers. Case 1 involved a 17‐year‐old never‐smoking girl with no medical history. Chest computed tomography revealed a 9 × 7 mm ground‐glass nodule in the left lung. Case 2 involved an 18‐year‐old man with no smoking history but bilateral pneumothorax. Chest computed tomography showed a 13 × 11 mm ground‐glass nodule in the right lung. In both cases, thoracoscopic wedge resection was performed, and the tumours were pathologically diagnosed as adenocarcinoma in situ. There was no evidence of recurrence for 2 years in Case 1, and for 1.5 years in Case 2.
