Fig. (4) Average PPAR-γ-positive rate. Results are shown as mean and standard deviation (SD). DDLS-WDLS: Area of WDLS in dedifferentiated liposarcoma. * P<0.05: Positive rate was significantly higher in MLS, PLLS, DDLS and WDLS in DDLS than in lipoma. # P<0.05: Positive rate was significantly higher in MLS, M/RLS, PLLS, DDLS and WDLS in DDLS than in WDLS.
