Background : Surgery for young patients（i.e., <２０ years of age）with early-stage lung cancer is extremely rare. To the best of our knowledge, only a few cases of lung cancer initially presented with spontaneous pneumothorax. Here, we report a case of AYA（adolescent and young adult）-generation lung cancer in a patient who presented with spontaneous pneumothorax.
Case : An １８-year-old male was admitted to our hospital for new-onset left pneumothorax. Chest computed tomography incidentally revealed a pure ground-glass nodule（pGGN）in the left lower lobe（S８）with a bulla near the nodule. While chest tube drainage improved his condition, pneumothorax recurred two weeks later, prompting surgical for video-assisted partial resection of the left lung. Intraoperative findings showed that the bulla and nodule were distant. Histopathologic analysis was consistent with a diagnosis of adenocarcinoma in situ with a bleb.
Conclusion : This study highlights the importance of considering the possibility of lung cancer in patients with irregular chest shadows, even those less than２０years of age. Computed tomography plays an important role in the diagnosis of lung cancer in patients with spontaneous pneumothorax.
