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.
Features include very common findings: Subcutaneous nodule; and sometimes findings: Gastrointestinal dysmotility and Abnormal renal physiology.
