SPS serrated polyposis syndrome, SSL sessile serrated lesion, HP hyperplastic polyp, TVA tubulovillous adenoma, TA tubular adenoma, TSA traditional serrated adenoma, LGD low grade dysplasia, HGD high grade dysplasia. The World Health Organization (WHO) for diagnosis SPS of 2010’s criteria: criterion no.1 refers to at least five serrated polyps proximal to the sigmoid colon, two of which are larger than 10 mm in diameter; SPS criterion no. 2 refers to any number of serrated polyps occurring proximal to the sigmoid colon in an individual with a first-degree relative with SPS; SPS criterion no. 3 refers to more than 20 serrated polyps of any size distributed throughout the colon. The WHO’s 2019 criteria: SPS criterion no. 1 refers to five or more serrated lesions/polyps proximal to the rectum, all being ≥5 mm in size, with at least two of which are larger than 10 mm in diameter; SPS criterion no. 2 refers to more than 20 serrated lesions/polyps of any size distributed throughout the colon, with ≥5 being proximal to the rectum
