THERE are many sites devoted to pathology. These are a few:
Pathmax: the most compendious listing of literally hundreds of pathology-related web-sites. This is the place to begin: search here for almost any kind of online pathology resource. The only problem is the embarrassment of riches, so that it may be difficult to distinguish the really worth-while sites.
Iowa Virtual Slidebox: Manipulate and examine digitized histopathology slides online via a Java application.
Immunoquery: Ask a question about immunohistochemical staining.
