Abstract

A rare case of mixed-type liposarcoma arising in deep soft tissue of the right thigh of a 45-year-old female patient is reported. The neoplasm was completely excised and was composed of an irregular admixture of areas of atypical lipomatous tumor/well-differentiated liposarcoma of the lipoma-like subtype with areas of myxoid/round cell liposarcoma. An amplification of the MDM2 and CDK4 genes respectively in the atypical lipomatous tumor/well-differentiated liposarcoma areas was detected by fluorescence in situ hybridization (FISH) analysis, and translocations of the CHOP and FUS genes were detected by FISH analysis in the myxoid/round cell liposarcoma areas.
