HISTOPATHOLOGIC FEATURES OF VILLOUS DYSPLASIA OF SUPERFICIALEPITHELIAL CELLS OF GASTRIC MUCOSA FROM BIOPSIED

cases of villous dysplasia of superficial epithelial cells of the gastric mucosa from biopsied and 4 cases early papillary adenocarcinomas were studied histopatholoically. Results showed thatthe papillary adenocarcinoma could be related to the villous dysplasis closely, particular Ⅲ leveldysplasia arising transition period from dysplasia to the course of the canceration of the gastric mucosa. Histopathologic features of villous dysplasia of superficial epithlial cells of the gastric mucosafrom bilpsiy was formed, because super-ficial epithelial suffered from effect of mutant and carcinogenic substans, losed normal different. Through the analysis of histopathologic feature, a conclusioncan be made that villous dysplasia might be an imPOrtant precancerous lesion of the papillary adenocarcinoma of the stomach. The data show that villous dysplasia of superficial epithelial of thegastric mucosa could be often merged atrophic gastritis.
