Essentially yes, but not like an attending and a first year resident. More like a fellow and an attending, more collegial and they are essentially confirming your thoughts to make you feel better about it or suggesting subtle points to fine tune things (rather than just telling you what it is). If you are uncomfortable making a diagnosis on your own then you show it to someone before you sign it out for confirmation. This is wise and does not show weakness. Sometimes this will even make clinicians feel better too since if you are new they don't know you (i.e. trust you) and it may prevent a phone call later.
There is NO PATHOLOGIST who is straight out of training who will not need to show some cases. Hell, experienced pathologists show cases all the time (you just may not see it in residency since they usually will not tell you they are going to share the case with a more senior pathologist after you leave sign out). Even if you have done a surgpath fellowship, it doesn't make you Juan Rosai and the same rules apply. To not do so is reckless. If a group hires someone straight out of training they expect this. In fact, I would say if you hire a new graduate and they are not showing cases then be very afraid, and also be concerned that they are not worried about the quality of their work. Moreover, in many private practice groups there are even certain cases that, as a rule, get automatically shown to another group member for confirmation regardless of who is signing it out (at my place it is breast needle core biopsies and most pancreas cases).
