MARTINEZ, Yolette et al. Adenomas aserrados: otro precursor de carcinoma de colon. Gen [online]. 2011, vol.65, n.4, pp.361-363. ISSN 0016-3503.

This study includes 12 consecutive patients who had a colonoscopy performed between Mar 2009 and May 2010 (10/83,33% females, 2/16,67% males), finding sessile lesion have a predilection for the proximal colon, pits patterns I - II (crypt dilatation and horizontal extension of crypts immediately above the muscularis mucosae). The application of this new technology electronic chromoendoscopy combined with high resolution endoscopy has promising areas of development in the description of pathologic mucosal changes and microvessels. This advanced technology allows an increased correlation between the images processed and the histological results. The serrated pathway neoplastic encompasses a morphologically and molecularly distinct group of colorectal neoplasms and represents an alternative molecular pathway to colorectal cancer. The sequence appears to begin with a non-dysplastic serrated polyp to a serrated adenoma and ultimately to carcinoma. Morphological and molecular studies are distinguishing a separate evolutionary pathway for colorectal cancer with extensive DNA methylation, mutation of BRAF and microsatellite instability.
