Overview

NCI Definition: A locally aggressive malignant neoplasm composed of mature adipocytes showing cell size variation and nuclear atypia. It is often associated with the presence of hyperchromatic multinucleated stromal cells, and varying numbers of lipoblasts. There are three histologic subtypes, sclerosing, inflammatory, and spindle cell liposarcoma. These tumors do not usually metastasize unless they undergo dedifferentiation. [1]

Well differentiated liposarcomas most frequently harbor alterations in MDM2 and CDK4 [2].

Most Commonly Altered Genes in Well Differentiated Liposarcoma

MDM2 Amplification and CDK4 Amplification are the most common alterations in well differentiated liposarcoma [2].
