Serrated polyposis syndrome, previously known as hyperplastic polyposis syndrome, is an uncommon condition characterized by the presence of serrated (colonic) polyps (hyperplastic polyps, sessile serrated adenomas), probably represents several distinct pathologies and is associated with an increased risk of colorectal carcinoma.[1]
No specific gene mutation for the syndrome is identified as of 2012.[2]
WHO definition
One of the following three:[2][3]
- >=Five hyperplastic polyps proximal to the sigmoid colon with two of the five >=10 mm.
- One hyperplastic polyp proximal to the sigmoid colon, in someone with a first degree relative with the syndrome.
- >20 hyperplastic polyps through-out the colon, i.e. not all can be rectal polyps.
