A 56-year-old woman presented at our hospital with dyspnea and weight loss. Computed tomography showed a giant mass in the anterior mediastinum and both thoracic cavities, which was about 30 cm in diameter. We diagnosed the mass as liposarcoma, and planned resection based on radiological findings. We prepared extracorporeal membrane oxygenation to avoid ventilation failure and circulatory collapse at the introduction of general anesthesia and during surgery. The tumor was completely resected by clamshell incision, measured 38 cm, and weighed 2855 g, pathologically diagnosed as dedifferentiated liposarcoma. She has been followed up for two years since surgery without recurrence.
