Pulmonary chondromatous hamartoma with pleural dissemination: report of a case

We herein describe a very rare case of pulmonary hamartoma with pleural dissemination. A 77-year-old male was referred to our department for a further investigation of an abnormal chest radiograph. Chest computed tomography showed a 15 mm nodule in the left lung with small pleural nodules. Thoracoscopic resection of the nodules was performed, as the possibility of malignancy could not be ruled out. The intraoperative findings revealed a white nodule with a lumpy surface in the left lower lobe that had penetrated the visceral pleura. Several smaller nodules were found on the pleural surface. Pathologically, the pulmonary and pleural nodules were chondromatous hamartomas.
