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

Figure 5

The histomorphologic characteristics of high-grade neoplasia of epithelial cells. (a) H&E staining results showing evident dysplasia of hyperplastic epithelial cells, with cells morphologically columnar to cuboidal, large nuclei, increased nuclear cytoplasmic ratio, prominent nucleoli, and increased mitotic figures. Characteristic image at 100x objective magnification was shown. (b) Immunohistochemical staining results showing the expression of p53. Characteristic image at 200x objective magnification was shown.
