Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.).

[1] [2] This differs from most colorectal cancer, which arises from mutations starting with inactivation of the APC ...
