Recently, the COL1A1-PDGFB chimeric gene resulting from a reciprocal translocation, t(17;22), and/or a supernumerary ring chromosome, r(17;22), has been identified, not only in conventional dermatofibrosarcoma protuberans (DFSP) but also in areas of DFSP with progression to fibrosarcoma (so-called fibrosarcomatous transformation) (FS-DFSP).

These results strongly suggest that the COL1A1-PDGFB chimeric gene expression associated with DP, induces tumours formation through production of mature PDGFB, in an autocrine or paracrine way.

This finding is in line with previous studies, and suggests further that not only the COL1A1/PDGFB fusion gene formation but also the role of DNA copy number gains in the 17q and 22q regions is crucial per se in the pathogenesis of DFSP.

Because COL1A1 exon 29 has been involved previously in gene fusion with PDGFB exon 2 in several cases of adult or infantile DP presenting either t(17;22) or ring chromosomes, our results support the concept that DP, GCF, and BT are morphologic variants of a same entity, rather than distinct tumors.

The novel fusion partners appear well suited to drive USP6 transcription in the bone/mesenchymal context: osteomodulin is expressed strongly in osteoblastic lineages, and the COL1A1 promoter has an oncogenic role in the mesenchymal cancer dermatofibrosarcoma protuberans.

The most frequent molecular abnormality observed in dermatofibrosarcoma protuberans (DFSP) is the formation of a supernumerary ring chromosome or translocation resulting in fusion of the gene encoding the alpha-chain of type 1 collagen, COL1A1 from 17q22, to the platelet-derived growth factor beta-chain, PDGFB gene from 22q13.
