Cases

Cases, also learning with simulated cases and interactive cases, is a part of onlinepathology that is focused on individual specimens.

The cases presented usually do not exactly mirror the details behind the pictures. The reason they aren't exactly like real life is: real life often isn't a good test, e.g. if the requisition say Peutz-Jeghers syndrome and the specimen is polyps... it isn't hard to diagnose the Peutz-Jeghers polyps.

Objective

The objective here is to simulate the decision making in pathology practise.

There are opportunities to look for more history, order special stains, order immunostains, order molecular testing for translocations, and ask a colleague -- before clicking on diagnosis to see if one is correct.
