The dataset consists of 101 H&E-stained colon whole slide images (WSI) - 52 abnormal and 49 benign cases. All significant abnormal findings identified are outlined and categorized into 15 types such as hyperplastic polyp, high grade adenocarcinoma and necrosis. Other tissue components such as mucosa, submucosa, as well as the surgical margin are delineated to create a complete histological map. In total, 756 separate annotations have been made to segment the different tissue structures and link them to ontological information.

Keywords: Pathology, Colon, Cancer, Whole slide imaging, Annotated.

Annotation

One physician was responsible for the manual annotations controlled by a second pathologist. Accurate annotations were made over the whole tissues. 756 separate annotations were made.

Following abnormal findings were annotated for the malign cases: acute and chronic inflammation, acute inflammation, adenocarcinoma, atrophy, chronic inflammation, diverticula, diverticulitis, dysplasia, edema, fibrosis, granulations tissue, hemorrhage, hyalinization, hyperplasia, hyperplastic polyp, inflammation, lymphoma, mucinous adenocarcinoma, necrosis, serrated adenoma, stasis, tubular adenoma, tubulovillous adenoma and ulceration.

Other areas annotated: abnormal, artifact, cecum, colon, colonic mucous membrane, colonic muscularis propria, colonic submucosa, colonic subserosa, descending colon, ileum, normal, rectum, sigmoid colon and transverse colon.

For the benign cases following areas were annotated: artifact, cecum, colon, colonic mucous membrane, colonic muscularis propria, colonic submucosa, colonic subserosa, descending colon, ileum, normal, rectum, sigmoid colon and transverse colon.

Pixel position scaling

Coordinates given are relative to the image width. To get the correct pixel position, X coordinates (and Y coordinates!) should therefore be multiplied with the image width.
