Spinal Metastasis of Well-Differentiated Liposarcoma Component in Retroperitoneal Dedifferentiated Liposarcoma Treated by Minimally Invasive Surgery

摘要

Case Generally, well-differentiated liposarcoma (WDL) has recurrence potential but lacks metastatic potential. We present a rare case of spinal metastasis of WDL component in retroperitoneal dedifferentiated liposarcoma (DDL) treated by tumor curettage and L1 laminectomy followed by percutaneous pedicle screw fixation. Histological examination showed metastasis of the WDL component of DDL. The patient was ambulatory until death.
