An edge case is where the program logic meets a boundary condition. A corner case is where you meet more than one boundary condition at once.

Edge cases are things you should test for in your unit tests because they are a very common place for bugs to be. Corner cases are usually talked about in terms of "I found a bug, but it is a bit of a corner case so it might not be worth fixing", that is, it will be encountered very rarely.
