You mean, other non-pathology specialties using tissue, slides, or reports you generated in publications without notifying or crediting you or your department?
When I was a resident, we couldn't really track who was doing what with our reports, which became part of the patient's record. Tissue, cassettes, slides, and images we generated, however, we could. If a clinician requested slides they could sign them out, however where I was at it was essentially impossible, or very expensive, for them to generate microscopic images without us. So when they asked we made it a habit of inquiring why they wanted images, and generally refused unless they agreed to properly credit us. As much as everyone wanted to play nice with the other specialties, if we didn't take a stand we were walked over night and day.
I can understand a clinician using reports and basic pathology "results" in a research project, without going above and beyond to credit every faculty member and resident who touched the specimens. But as soon as you're asked to do or provide something extra, you, or at least the department, should get properly credited.
If you mean they're requesting other stains or what have you which aren't usual diagnostic steps, then everyone needs to be on board ahead of time -- additional research-only studies have to be billed/paid for separately, and all the appropriate IRB approvals given.
