Well, I think you're being a bit overdramatic here. Obviously, asking questions is encouraged. But at any program, if you ask questions like, "What's a prostate?" you are not going to get much of a response. And looking up clinical histories is not scutwork. It mostly depends on who is at the computer, actually. It can happen in the context of signout, or can happen before signout. You don't get sent off to do this. You don't spend your day looking up clinical histories. You can spend your day doing whatever you want, it's just that on path it is often more self directed, and you have to take the initiative.
The thing is, many med students use a path rotation as an opportunity to leave early, unfortunately. So when a new student comes in, we give them the benefit of the doubt, but we don't expect much unless they take more initiative. But when someone comes to signout or wants to look at cases on their own, they obviously will be given more of an opportunity. If they want to help out on autopsies, that's fine. If they want to try cutting a frozen, that's good.
The thing is, you asked the question, "How much help can I be?" and I answered. They are not letting you cut frozens or letting you gross things in to be helpful. I didn't mean to imply that med students should stay out of the way and go put their face in a book instead of actively participating. That's silly. What I am saying is that you (as a student) aren't necessary as useful on pathology services, as you would be on medical or surgical services, so don't worry about "helping" and worry more about learning. Learning can obviously include technical things such as grossing and frozens! No one is going to make students do objectionable tasks like going to deliver slides to someone or run errands or leave signout to go find another doctor. You do much, much, much less scut (actually, you do NO scut) on pathology rotations.
I'm sorry if you don't think reading and learning about cases is a reasonable assumption for a student on pathology. If you have sat in on signout at all, you will realize that being prepared for signout by reviewing the cases and learning about the differentials is extremely important.
I love it when a student is around who is interested in pathology and eager to learn. It makes things a lot more interesting, and I learn more when I can help teach. So sometimes I go over cases with the student before or after signout, etc. But that is the rare student!
