Sarcome fibromyxoïde de bas grade : une étude clinico-pathologique de 7 cas

Differential diagnosis of LGFMS should include intramuscular myxoma, myxoid liposarcoma, myxoid variant of dermatofibrosarcoma protuberans and low grade myxofibrosarcoma. The chimeric FUS/CREB3L2 gene seems to be specific for LGFMS and its expression in the t(7;16)(q33p11) is a useful tool for the differential diagnosis. We report a unique case with areas of high grade sarcoma, MFH type, and areas similar to sclerosing epithelioid fibrosarcoma.
