Summary[edit]

Description
English: Intermediate 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.
