Fixation
Generally 10% neutral buffered formalin. Fix all thyroids at least overnight to avoid artifactual nuclear atypia.[1]

Gross processing
Selection and trimming
- Weigh[1]
- Measure each lobe and isthmus in 3 dimensions, respectively.[1]
- Ink outer surface:Template:Ink note[1]
Hemithyroidecomy (lobe + isthmus) or lobectomy, including completion thyroidectomies: Use separate colors over the cut surface and the outer “capsular” surface.<ref group="notes" name="coloring">Separate coloring allows to distinguish the thyroid margin (continuous with the other lobe) from the peripheral margin (towards soft tissues).
None of the outer “capsular” surface should be inked like the cut surface.[notes 1]
