Abstract
|
|
|
|
True mixed liposarcomas are extremely rare tumors. We report here on a case of mixed liposarcoma that was composed of well differentiated and pleomorphic liposarcoma. A 76-year-old man presented to us with a mass in his left upper arm. This lesion had been there for twenty years, it was recently growing rapidly and had doubled in size during the recent 2 months. The MR image showed a mass composed of a fat component and a soft tissue component with necrosis. The old fat component was revealed as well differentiated liposarcoma, and the recent growing soft tissue component was revealed as pleomorphic liposarcoma. The two components showed different immunohistochemical results for MDM2.
