1. Fig. 3. A photomicrograph shows the combination of the numerous, inter-anastomosing vascular spaces and more solid, spindle-cell areas effacing the normal lobular architecture (Hematoxylin & Eosin staining, × 200) (a). On immunohistochemical staining, tumor cells are diffusely and strongly positive for CD34 (b) and focally positive for factor VIII (c). The estimated Ki-67 index in the cellular areas is approximately 40% (× 400) (d).
