From: Dedifferentiated chondrosarcoma with leukocytosis and elevation of serum G-CSF. A case report
Dedifferentiated chondrosarcoma is characterized by the coexistence of conventional chondrosarcoma (top; left side) and dedifferentiated components (top; right side). Dedifferentiated components are composed of atypical spindle cells in a storiform pattern, resembling MFH (bottom; left), or osteosarcoma with lace-like osteoid formation (bottom; right). Asterisk (*) shows artificial space. (Hematoxylin and Eosin original magnification top; × 50, bottom; × 180).
