Background. Lung hamartoma with lung cancer has sometimes been reported. Case. Chest computed tomography (CT) in a 70-year-old woman was revealed a 2.0×1.5 cm nodule in the right S3. It was considered to be a lung hamartoma. Periodical CT examination was conducted, and 24 months later, a lesion with ground-glass opacity (GGO) was found in the same lobe as the lung hamartoma. The tumor was resected using video-assisted thoracic surgery (VATS). The post-operative pathologic diagnosis was bronchioloalveolar carcinoma of the lung. After the operation, the patient made a favorable recovery, and has maintained in good condition without recurrence for 5 years to date. Conclusion. The relationship between lung hamartoma and lung carcinoma is not clear. We consider that periodical CT examination contributes to identifying such tumors.
