Figure 7. Photomicrograph (original magnification, x150; hematoxylin-eosin stain) shows the typical bimorphic appearance of mesenchymal chondrosarcoma, with a malignant cartilaginous component on the right (C) and an abrupt transition to a more cellular vascular portion on the left (H) with hemangiopericytoma-like features. Arrows = vascular channels.
