Pleomorphic liposarcoma
Definition
Pleomorphic liposarcoma (PLS), the rarest subtype of liposarcoma (LS), is an aggressive, fast growing tumor located usually in the deep soft tissues of the lower and upper extremities. It is characterized by a variable number of pleomorphic lipoblasts and, in contrast to dedifferentiated liposarcoma, it lacks any association with well-differentiated liposarcoma.
