Figure 1: (a) Classical dedifferentiated liposarcoma (DDLS) (Case 5). (a) Interface of well-differentiated liposarcomatous (WDLS) component (adipocytic type) with DD component. (hematoxylin and eosin, ×100). (b) WDLS component comprising lipoblasts (hematoxylin and eosin, ×400). Inset: Distinct lipoblast with atypical nucleus indented on its surfaces by fat vacuoles. (hematoxylin and eosin, ×1000). (c) Dedifferentiated (DD), "non-lipogenic" component comprising highgrade pleomorphic sarcoma with pleomorphic cells and numerous mitotic figures, including atypical forms. (hematoxylin and eosin, ×400). (d) S100 positivity in lipoblasts (arrows) (Case 6). (Diaminobenzidine, ×400)
