En elakartad tumör som härstammar från primitiva eller embryonala lipoblastceller. Den kan bestå av väldifferentierade fettceller eller kan ha dedifferentierats: myxoidliposarkom, rundcellig eller pleomorf, oftast tillsammans med ett rikligt utvecklat nätverk av kapillärer. Tumöråterkomst är vanlig, och dedifferentierade liposarkom metastaserar till lungor och serösa ytor.
A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed)
