[The colorectal adenoma-carcinoma sequence: the limits between polypectomy and intestinal resection].

According to a clinic case, the authors pointed out the role of histological diagnosis in the therapeutic approach of large intestinal adenomas. In order to identify those lesions which can metastasize, having exceeded the muscularis mucosae and having invaded the submucosa, rigorous histological standards must be performed. Intestinal resection versus polypectomy is determined only according to the involvement or not of the muscularis mucosae.
