ABSTRACT

A 68-year-old woman was accidentally found to have a tumor in the upper lobe of the left lung on chest imaging. Chest computed tomography findings suggested a pulmonary hamartoma; however, a giant pulmonary cyst was detected on the peripheral side of the tumor. Bronchoscopy revealed marked telangiectasia in the bronchial mucosa near the tumor. Because of the large size of the tumor and the risk of developing pneumothorax, infection, or hemoptysis, a thoracoscopic left upper lobectomy was performed. Even when a benign tumor is suspected, if the tumor is large, it may cause various complications due to compression of the surrounding tissue. Hence, surgical resection should be considered.
