FUS and myxofibrosarcoma: Except for SPL and ASPLT, the differential diagnosis can be made based on the following: i) FUS and EWSR1 rearrangements detected by fluorescence in situ hybridization in myxoid liposarcomas (13); ii) no characteristic markers and comprehensive diagnosis in myxofibrosarcoma (14); and iii) the presence of encapsulation and alternating Antoni A and B regions in the schwannoma (9).
