title: [Non-chondromatous hamartoma].
abstract: A 69-year-old female visited our hospital because of dyspnea. Chest X-ray showed an abnormal shadow in the right lower lung field. Chest computed tomography (CT) showed a round, well-circumscribed, homogenous subpleural nodle of 8 mm in diameter in the right lower lobe, which had no calcification and no pleural indentation. Bronchofiber scope, abdominal CT, brain magnetic resonance imaging (MRI), bone scintigraphy could not establish definitive diagnosis. Scince the possibility of malignancy could not be excluded throughout, video-assisted thoracoscopic surgery was performed to obtain confirmed diagnosis. Pathological examination revealed non-chondromatous hamartoma of the lung. Non-chondromatous hamartoma should be considered in the differential diagnosis of pulmonary nodles. We report a rare case of non-chondromatous hamartoma.
