Major histopathological subtypes of canine colorectal tumors investigated.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Shown from top to bottom are H&E staining images for normal colon (mucosa, submucosa, and muscle layers as indicated), colorectal adenoma, and colorectal adenocarcinoma. In the adenoma (middle), there is preservation of a distinct basement membrane (arrows). In the adenocarcinoma (bottom), a section of the basement membrane (small arrows) has been disrupted and penetrated through by neoplastic cells invading the submucosa (large arrow).
