Introduction: Serrated lesions are considered precursors of colorectal adenocarcinomas. Studying them in their initial phases is important when thinking about cancer prevention, when they are hyperplastic lesions, or sessile serrated lesions. Objective: To carry out an integrative review of the literature to compare the endoscopic and histopathological characteristics in the initial phases of the disease, with the intention to help understand colorectal cancer. Methods: Integrative literature review based on existing analysis material on the digital platforms SciELO – Scientific Electronic Library Online, Google Scholar, Pubmed and Scopus. The beginning was the search with the following descriptors: “serrated sessile lesions, colorectal carcinoma, superficial lesions”, with AND or OR search, considering the title and/or abstract , and subsequently including only those with the highest correlation for reading the full texts. Results: 39 articles were included. Conclusion: The majority of superficially elevated serrated lesions measuring more than 5 mm and resected by colonoscopies are hyperplastic. They occur throughout the colon and rectum, while the serrated sessiles are preferentially located in the proximal colon. Hyperplastic ones generally do not present dysplasias and sessile serrated ones can have them intensely.
