[Macroscopic and histopathological aspects of atypical gastric epithelium].

Atypical Epithelium is a localized lesion, which has histological and macroscopic findings similar to gastric cancer. In this paper we evaluated 44 cases of atypical epithelium studied and treated in our institute. We found 3 cases of atypical epithelium associated with early gastric cancer. That is 2.66% of the total of all cases. We established the relationship of these lesions and following variables: age, size, localization, macroscopic shape and intestinal metaplasia. We found atypical epithelium in patients older than 50 years old, most of then smaller than 2 cm., localized in antrum and body gastric, and macroscopically were slight elevated lesions. Histologically all of them had intestinal metaplasia.
