[Molecular diagnosis of liposarcomas: identification of the chimeric genes FUS/CHOP and EWS/CHOP].

This paper presents the results of an analysis the chimeric genes FUS/CHOP and EWS/CHOP in patients diagnosed as having liposarcoma in order to make a differential diagnosis in both soft tissue tumors and various variants of liposarcoma. Liposarcomas were found in 5 of 7 cases of primary tumors: 4 chimeric transcripts of the FUS/CHOP type (5-2), a variant of alternative splicing of the FUS/CHOP type (5-2) with depletion in 14 p.n.
