Following are general notes on selection and trimming in pathology.
Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
- Generally measure estimated volume or 3 dimensions for samples greater than 0.4 cm in greatest dimension.[notes 1]
- ((Note the color of the sample, even when unremarkable.((
- Generally, use inking for resection margins where cancer radicality is important.Template:Ink note Excisions made by laser do not need inking on the excision surfaces, since the coagulated surface can be easily identified in the microscope.[1]
- (Preferably photograph or make a drawing where slices have been taken.)[2]
- Remove any surgical stitches from samples before microtomy.
- (At least for larger samples, consider looking for medical imaging or biopsy reports in order to better guide the process.)[3]
- Generally, strive to make slices perpendicular to visible interfaces of relevant tissues.
