Background. Although some adenocarcinomas grow slower than other histological types of lung cancer, a lung cancer with a more than 10-year clinical history is rare. Case. A 48-year-old woman was admitted to our hospital because of a liver tumor detected by a medical check up. Chest CT before the liver surgery showed another abnormal lung shadow and she consulted us after the surgery. The same pulmonary lesion was detected on a chest CT about 10 years previously. Video-assisted thoracoscopic surgery (VATS) was first scheduled for a partial resection. Diagnosis of the frozen section showed lung cancer, which led us to perform additional resection of the right middle lobe and a lymph node dissection (ND2a). Histologically, it was diagnosed as mucinous adenocarcinoma and the final pathological stage was pT1N0M0 stage IA. Conclusion. We encountered an adenocarcinoma of the lung which had a clinical history of about 10 years before resection. It is necessary to remember the possibility of a very slow-growing lung cancer when we find an abnormal shadow of the lung that grows gradually over time.
