In addition, a following cytogenetic report demonstrated an identical recurrent t(7;16)(q34;p11) translocation and fusion between the FUS and CREB3L2 genes in LGFMS and HSTGR, which was confirmed by multiple studies regarding these subtypes of fibrosarcoma, thereby providing genetic proof that these two tumors are variants of the same entity (12). This evidence concerns the gene FUS and fibrosarcoma.
