Resection of giant mediastinal liposarcoma via '{dashv} shape incision

Primary mediastinal liposarcomas are extremely rare conditions often resected through standard median sternotomy or lateral thoracotomy. However, the management of a very huge mediastinal tumor involving hemithorax through these two common surgical approaches is always challenging. Herein, we report a case of applying median sternotomy with a sternum transection plus a right fourth intercostal thoracotomy (' shape' incision) to resect a giant primary anterior mediastinal liposarcoma extending into the whole right thorax. The final pathological diagnosis was a well-differentiated liposarcoma. The patient experienced an uneventful recovery. The ' shape' incision is a good backup for the extension of standard median sternotomy and provides a better exposure for both mediastinum and hemithorax.
