Figure 3

(a) The intravenous tumor (H&E magnifying lens). (b) Vessel endothelium cells and vascular smooth muscle layer covered the intravenous leiomyoma (H&E 40×); an enlarged view of the area in Figure 3(a) is surrounded by a large black box. (c) Tumor cells stained strongly for positive Alcian blue at a pH of 2.5 (200×); an enlarged view of the area in Figure 3(a) is surrounded by a small black box. (d) Alcian blue staining disappears after hyaluronidase digestion (200×); the same area as that in Figure 3(c) is shown.
