UniToPatho

UniToPatho is an annotated dataset of 9536 hematoxylin and eosin stained patches extracted from 292 whole-slide images, meant for training deep neural networks for colorectal polyps classification and adenomas grading. The slides are acquired through a Hamamatsu Nanozoomer S210 scanner at 20× magnification (0.4415 μm/px). Each slide belongs to a different patient and is annotated by expert pathologists, according to six classes as follows:

  • NORM - Normal tissue;
  • HP - Hyperplastic Polyp;
  • TA.HG - Tubular Adenoma, High-Grade dysplasia;
  • TA.LG - Tubular Adenoma, Low-Grade dysplasia;
  • TVA.HG - Tubulo-Villous Adenoma, High-Grade dysplasia;
  • TVA.LG - Tubulo-Villous Adenoma, Low-Grade dysplasia.
