Histomorphological Characteristics and Pathological Types of Hyperproliferation of Gastric Surface Epithelial Cells

Figure 4

The histomorphologic characteristics of low-grade neoplasia of epithelial cells. (a) H&E staining results showing mild to moderate dysplasia of gastric epithelial cells, which were located at the base of the glandular epithelium, with increased nuclear length, retained polarity, and visible mitoses. Characteristic image at 100x objective magnification was shown. (b) Immunohistochemical staining results showing the expression of ki-67. Characteristic image at 200x objective magnification was shown.
