The resected tumor comprised pleomorphic tumor cells containing
lipoblastic cells with vacuolated cytoplasms. Immunohistochemical
analysis showed diffuse positivity for MDM2 in tumor cells.
Histopathological diagnosis of the tumors was dedifferentiated
liposarcoma (Fig. 3). On postoperative day 14, the patient was
discharged and followed up without adjuvant chemotherapy or
radiotherapy. He has survived for 8 years since the initial surgery and
2 years since the second surgery.
