The sections shows colorectal-type mucosa with a tubule-forming epithelium that has | |||
cellular pseudostratification and enlarged hyperchromatic nuclei, from the crypt base to | |||
the luminal aspect (dysplasia). | |||
No cribriforming of glands, epithelial budding or intraluminal papillary tufting is | |||
identified. Goblet cells are present in the dysplastic epithelium. Dysplastic nuclei have | |||
an ellipsoid-shape and basally stratified. | |||
Finger-like epithelial projections (villi) are present and comprise approximately 55% of | |||
the dysplastic tissue. | |||
