Other categories of liposarcoma include well-differentiated; dedifferentiated; round cell; and pleomorphic.[1] Round cell and myxoid liposarcomas are sometimes grouped together into one category known as myxoid/round cell liposarcoma (MRCLS).[2] 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.

Specifically, pleomorphic liposarcoma is the least common subtype with a high rate of recurrence and poor outcomes. Liposarcoma is soft tissue cancer that develops in fat cells. It can begin in any part of the body, but it usually forms in belly, legs or arms. Liposarcoma most often occurs in the fat layer just below the skin or in the soft tissues (muscles, fat, tendons and nerves).
It can grow faster than well-differentiated tumors, and it's more likely to spread to other parts of your body. Its cells can form a unique
When myxoid liposarcomas have a purely cystic appearance at MR imaging, both contrast-enhanced MR imaging and US are useful in the differential diagnosis. Myxoid liposarcomas with a cystic appearance at MR imaging usually appear as complex, hypoechoic masses that do not meet the criteria for a simple cyst at US (,,,,, Fig 4).
