摘要
the authors report the case of a 28-year-old female patient with a giant cell tumor originating from the rib. the tumor, measuring 25 ℅ 17 cm, occupied the entire hemithorax and caused atelectasis of the left lung. this tumor was a benign mesenchymal neoplasm, which rarely affects the ribs. a thoracotomy involving en bloc resection of the chest wall and tumor was performed. despite the large dimensions of the tumor, complete resection was possible, and lung function was restored.
