NCIt definition : A low-grade, late-metastasizing variant of fibrosarcoma characterized by alternating
fibrous and myxoid areas and a whorling growth pattern. The neoplastic cells have
a spindle morphology, and lack hyperchromasia or significant nuclear atypia. Approximately
40% of cases show the focal presence of collagen rosettes. A t(7;16)(q33;p11) translocation
has been identified in the majority of cases, associated with the presence of FUS-CREB3L2
fusion protein. Rare cases carry the t(11;16)(p11;p11) translocation which is associated
with the presence of the FUS-CREB3L1 fusion protein.;
