What is the difference between an angiolipoma and liposarcoma?

Liposarcomas look like angiolipomas. However, while angiolipomas and liposarcomas look similar, angiolipomas tend to grow slowly and are well-defined. Liposarcomas tend to be larger, grow more rapidly and are not as well-defined, meaning their edges may be hard to distinguish.

Liposarcomas are soft tissue cancer that develop in fat cells. Lipomas are benign soft tissue tumors. They grow slowly and aren’t cancerous, and they usually don’t need treatment.

Your healthcare provider can help decide if a biopsy or imaging is necessary to tell them apart.
