Low-Grade Fibromyxoid Sarcoma, 16p11 (FUS or TLS)
Rearrangement, FISH, Tissue
Clinical Information: Low-grade fibromyxoid sarcoma (LGFMS) is a rare malignant soft tissue
tumor characterized by a bland fibroblastic spindle cell proliferation arranged in alternating fibrous and
myxoid areas, with or without giant collagen rosettes. These tumors are characterized by the chromosome
translocation t(7;16)(q33-34;p11), which results in the fusion of FUS (also called TLS) on chromosome
16 to CREB3L2 (also called BBF2H7) on chromosome 7. Greater than 70% of LGFMS are
cytogenetically characterized by this translocation. In rare cases, a variant t(11;16) (p11;p11) has been
described in which FUS is fused to CREB3L1 (OASIS), a gene structurally related to CREB3L2. Testing
of FUS locus rearrangement should be concomitant with histologic evaluation, and positive results may
support the diagnosis of LGFMS.
Useful For: Aiding in the diagnosis of low-grade fibromyxoid sarcoma when used in conjunction with
an anatomic pathology consultation
Interpretation: A neoplastic clone is detected when the percent of cells with an abnormality exceeds
the normal cutoff for the FUS probe set. A positive result is consistent with the diagnosis of low-grade
fibromyxoid sarcoma (LGFMS). A negative result suggests that a FUS gene rearrangement is not present,
but does not exclude the diagnosis of LGFMS.
