title: Primary chondrosarcoma of the lung recognized as a long-standing solitary nodule prior to resection.
abstract: As the use of computed tomography (CT) increases, incidental lung nodules have become a clinical issue that is being addressed more than before. We detected a solitary lung nodule which was smooth-margined, round-shaped, 11 mm in size. Follow-up for 18 months after initial detection by chest CT did not show any interval change. To make a definitive diagnosis, video-assisted thoracic surgery was performed and the lesion was diagnosed as myxoid chondrosarcoma. In the 6-year postoperative follow-up, annual chest CT and bone scintigram did not reveal any abnormality, which excludes the possibility of a latent primary site other than the lung. Therefore, we considered the present case being of pulmonary origin. Accordingly, even though the lesion appeared unremarkable, surgical resection of solitary lung nodule should not be discouraged.
