YES! I have gotten quite irritated at a reasonably close well known academic center because they have repeatedly issued minor disagreements on cases I had originally signed out - these are disagreements that are within the realm of opinion and not really evidenced based (try telling THAT to the patient!). You lose fans by doing that. Another person in my group is even more cheesed off and retaliates by sending the cases for a third opinion (which usually agrees with him) and then faxing the reports to all the clinicians involved.
If you have a good relationship with clinicians, this becomes less important. The clinician will trust you, and any discrepancies can be dealt with by a conversation discussing the significance (or lack of significance) and possibly by getting another opinion. But in the eyes of the patient, who are they going to think is "correct"? The local pathologist? Or the eminent "professor" at the UNIVERSITY? Even if said "eminent professor" has two months experience out of fellowship?
Now, most of our work does not get reviewed by academics. The routine stuff rarely does. It is the weird stuff that does, but that's the stuff that we are more likely to send out anyway. Bizarre unclassifiable lymphomas. Sarcomas that look like they could be reactive proliferations. Unclassifiable interstitial lung crap. Indeterminate follicular thyroid lesions.
And of course, to top it all off, when the academic finds that another academic agreed with you, they will make some bull**** excuse like, "oh, well we didn't have all the clinical information we needed" or something like that, a subtle jab trying to deflect blame back at you anyway.
What the good academics realize is that cultivating good relationships with community pathologists not only gets you respect but it also gets you consults. We in the community can usually pick who we send our cases to.
