Myxoid liposarcoma (MLS) is a rare subtype of soft tissue sarcoma that distinguishes itself from conventional subtypes through its propensity for extrapulmonary metastasis. The distinctive magnetic resonance imaging (MRI) characteristics of MLS render it an invaluable tool for identifying primary and secondary lesions. Pathologically, MLS is characterized by the FUS-DDIT3 gene fusion. Accurate diagnosis, facilitated by MRI and pathological assessment, is critical for prognostication and the formulation of appropriate treatment strategies. Surgery remains the cornerstone of local management for MLS. The combination of surgery and radiotherapy can significantly reduce the local recurrence rate in MLS, as it is highly sensitive to both radiotherapy and chemotherapy. Additionally, for high-risk MLS cases with a large tumor diameter, chemotherapy has been shown to improve survival. The comprehensive treatment approach for MLS demonstrates superior local recurrence rates and survival rates compared to most soft tissue sarcomas. Current research focuses on developing effective therapies for unresectable or advanced disease based on genomic and phenotypic characteristics as well as the immune-tumor microenvironment. © 2024.
