Abstract:A differenttiated liposarcoma was first described in1979,and its definition has been recently extended.We found an undiagnised anterior mediastinal mas in a 56 -year-old man for whom we performed a complete tumor resection through median sternotomy.Microscopic examination revealed that the mass was primarily a low-grade,dedifferentiated liposarcoma,with a partial high-grade area.Occurrence of dedifferentiated liposarcoma in the anterior mediastinum is rare.We didi not perform any adjuvant therapy.Three years after the surgery,the patient is alive without disease.In lipoma-like,well-differentiated liposarcoma cases,we should consider the possibility of dedifferentiated liposarcoma if a mild, atypical spindle cell component is found.
