Colon and rectum
Historically, serrated polyposis has been called hyperplastic polyposis; however, the term “serrated polyposis” is preferred, given the common presence of sessile serrated adenoma/polyp (SSA/P)
in this process

Differing criteria to define serrated polyposis have been suggested, although all are empirical and the described categories may represent different diseases. Definitions include: (1) at least five serrated polyps proximal to the sigmoid colon with two or more of these being > 10 mm; (2) any number of serrated polyps proximal to the sigmoid colon in an individual who has a first-degree relative with serrated polyposis; or (3) > 20 serrated polyps of any size, but distributed throughout the colon
