Figure 3: (a) Photomicrograph showing many spindle cells with eosinophilic cytoplasm. Note the tumor cells are in continuity with the vessel wall (H and E, ×20); (b) SMA positive tumor cells in continuity with the vessel wall and also in large areas away from the vessels (SMA stain, ×20); (c) reticulin positive fibers are also in continuity with vessel wall and involving large areas of the tumor (reticulin stain, ×20); (d) factor VIII positive tumor cells, close to vessel wall and also away from it (factor VIII Ag, ×40)
