Type of disease: Rare conditions
Liposarcoma is a tumor that arises from fat tissue. This tumor often occurs in the thigh, behind the knee, or in the abdomen, but it can be found in other parts of the body. Because a liposarcoma may grow into surrounding tissues or organs, it is considered a malignant tumor. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
