Abstract
Myxoid liposarcomas are rare malignant soft tissue tumors, representing a distinct entity due to their histological features and intermediate biological behavior. This report presents the case of a 31-year-old man who underwent surgery in 2020 for a lipoblastoma of the right thigh, which recurred as a histologically confirmed myxoid liposarcoma. MRI enabled precise characterization of the tumor. A carcinological excision with venous reconstruction and muscle coverage was performed. This case highlights the importance of MRI in the diagnosis of soft tissue tumors, the benefits of multidisciplinary management, and the necessity of prolonged follow-up after surgery.
