I am in my third Path rotation of my 4th year of med school. Already I've learned quite a bit, just from observing hours of sign-outs and reading up on cases now and then. My theory is that you will see the more common things over and over again throughout residency, so you will learn it even without trying. I'm personally trying to kick-start the learning process by keeping a running tab of the disease entities I see that I need to know more about, then, when I get some time to sit down, I read about them. Eventually I'll know enough about things that I don't need to jot them down anymore. Continue this process for four years and, voila, you're a Pathologist. Now some might say that you'll see the same disease processes frequently and never see some of the more rare entities. This might be the case at some programs, but at the ones I've seen, the more rare cases come up at unknown conferences, tumor boards, etc, even if they don't necessarily appear in the grossing room. So, while I agree that the amount of information we'll have to know is mind-boggling, I'm not stressing out about it since I think we'll have plenty of time, and I think my learning method will work for me.
