Background. Peripheral lung adenocarcinoma has been increasing dramatically throughout the post decade. Recently, it was reported that active fibroblastic proliferation in a tumor plays an important role in tumor progression. However, there have been few reports of CT follow-up of peripheral lung adenocarcinoma for several years. Case. the patient was a 67-year-old woman. Follow-up of computed tomography was performed every year and the tumor doubling time was 920 days in our case. After four years, CT-guided needle-biopsy resulted in well-differentiated adenocarcinoma. Operation was performed and the pathological finding was localized bronchioloalveolar cell type adenocarcinoma (Noguchi's type B). Conclusion. We reported a case of a slow-growing lung adenocarcinoma the size of which remained under 20 mm for four years.
