Abstract:
Although it is possible to classify gastrointestinal tract mucosal changes by numerous classifications that have been published over the last 20 years, none has been accepted worldwide for the daily diagnosis of biopsies. With respect of routine surgical specimen diagnosis, it is argued in the article that the intraepithelial neoplasia (IEN) level be based on the terms of benign (precursor) lesions. In addition, esophageal and gastric IENs classifications are proposed as well as the question of whether it is possible to extend this classification to the colon and rectum.
