A 50-year-old male was pointed out as showing a tumor shadow in the anterior mediastinum, which was irregularly enhanced. The tumor was diagnosed as a liposarcoma by CT-guided needle biopsy. No systemic metastases were found. We performed a complete resection of the tumor through a median sternotomy. The tumor was encapsulated and did not directly invade surrounding tissues. The tumor was 14×11×6 cm in size. The postoperative pathological diagnosis was mediastinal liposarcoma, myxoid type. He was well without adjuvant therapy at 8 months after surgery. The incidence of mediastinal liposarcoma is only 0.1% of all mediastinal tumors. Although he is expected to show long-term survival following complete resection, we have to follow his clinical course for a long period because this tumor often shows local recurrence.
