Primary pleomorphic liposarcoma of bone: A case report with literature review

Year: 2023

Type: article

Abstract: INTRODUCTION AND IMPORTANCE: Primary pleomorphic liposarcoma of bone is an exceedingly rare sarcoma. CASE PRESENTATION: We herein report the case of a primary pleomorphic liposarcoma of the distal femur in a 20-year-old female patient. Magnetic resonance imaging showed a 25.4-mm medullary necrotic tumor process in the lower third of the distal right femoral meta-diaphysis that was weakly enhanced after gadolinium injection. The patient first underwent an open biopsy. Microscopically, a pleomorphic liposarcoma were suspected. Immunohistochemically, tumor cells expressed the S-100 protein. Fluorescent in situ hybridization showed the absence of MDM2 gene amplification and the absence of EWING/PNET translocation. The diagnosis of primary pleomorphic liposarcoma of the bone was then retained. A wide resection and chemotherapy were performed. The patient died of liver metastasis after 8 months of follow-up. CLINICAL DISCUSSION AND CONCLUSION: Primary pleomorphic liposarcoma has no specific clinical or radiological findings. Histological diagnosis and molecular study are crucial tools for making an accurate diagnosis.
