pathology.jhu.edu/prostate This site was established to attempt to improve Gleason grading. The site contains a relatively brief tutorial program and has been shown to significantly improve Gleason grading by general pathologists and also by residents in pathology.

www.pathology.ks.se/egevad/gleason.html This site describes Gleason patterns 2-5 with 40 images, including an attempt to define lower and upper limits of patterns. It, too, has been shown to significantly improve Gleason grading.

http://129.240.38.9/norcyt/prostata/prost.htm This site provides low power images and high power fields from the same case. You are asked to give a Gleason score on a case and then the correct alternative is given together with a brief text.
