Case 2. Primary site. (a) H&E staining (original magnification × 40) (b) H&E staining (original magnification × 400). Circular shapes or short spindle cells are multiplied sparsely around the necrosis tissue. Brisk mitotic activity and atypical cells are observed. (c) Recurrent site H&E staining in iliac bone biopsy showing the same sarcoma component as the primary site (original magnification × 400). Case 3. Primary site. (d) H&E staining (original magnification × 40) (e) H&E staining (original magnification × 400). Inside the leaf-like structure covered by a layer of flattened epithelium, clear cytoplasm cells constitute a multi-nodular structure. (f) Recurrent site H&E staining shows spindle cells and abundant foam cells (original magnification × 400). ER: estrogen receptor; H&E: hematoxylin and eosin; PR: progesterone receptor
