Fixation
Generally 10% neutral buffered formalin. Fix all thyroids at least overnight to avoid artifactual nuclear atypia.[1]
See also: General notes on fixation
Gross processing
- Weigh[1]
- Measure each lobe and isthmus in 3 dimensions, respectively.[1]
- Ink outer surface,[1] at least if malignancy is suspected.[2]:Template:Ink note
Hemithyroidecomy (lobe + isthmus) or lobectomy, including completion thyroidectomies: Use separate colors over the cut surface and the outer “capsular” surface.[notes 1]
None of the outer “capsular” surface should be inked like the cut surface.[notes 1]
Intact total thyroidectomy: Separate colors for each lobe and the isthmus.
If no appreciable isthmus, Separate colors for each lobe.
Serially section the specimen at 3-4mm intervals,[3] such as follows:[1]
Hemithyroidecomy (lobe + isthmus) or lobectomy: Include isthmic orange margins in your transverse sections.
Intact total thyroidectomy: Transverse lobe sections and sagittal isthmus sections
Short/inconspicious isthmus: The isthmus can be included in the transverse sections.
