I agree with storm and joe here. I would venture to say that surg path is the one pathology rotation that has the potential to involve a lot of scut work. I would consider some of the grossing to be scut because one really learns surgical pathology by looking at the slides. Of course, one has to do the grossing to get to that point. And there are a lot of specimens where grossing provides valuable experience initially. However, there's got to be a point where you've done all the grossing you want to do and further grossing has little educational value. Nonetheless, the work has got to be done. But it would be tragic if you could not preview and signout the slides that you grossed; I hope that not too many places do this.
Now fortunately, at a lot of places there are PAs to help you out. PAs should gross small biopsies since I don't think this has hardly any educational value for the resident. Then ultimately, when you become an attending, you won't be doing much grossing (if at all); basically you will just look at and sign-out slides.
