Summary[edit]
| Summary | |
|---|---|
| Description | Very high magnification micrograph of a sessile serrated adenoma, abbreviated SSA, from the cecum removed during a colonoscopy. H&E stain.
SSAs are characterized by: basal dilation of the crypts, basal crypt serration, crypts that run horizontal to the basement membrane (horizontal crypts), and crypt branching. Unlike traditional colonic adenomas (e.g. tubular adenoma, villous adenoma), they do not typically have nuclear changes (nuclear hyperchromatism, nuclear crowding, elliptical/cigar-shaped nuclei). SSAs are considered pre-malignant lesions, i.e. precursors to cancer, and tend to be found in the right colon. Related images
