Fixation

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

Removal during autopsy

Sharply dissect the thyroid from the cartilage, starting at the posterior end of each lobe & working forward. Do not cut the isthmus. Try to find parathyroids.

edit

  • Weigh[2]
  • Measure each lobe and isthmus in 3 dimensions, respectively.[2]
  • Ink outer surface,[2] at least if malignancy is suspected.[3]

Serially section the specimen at 3-4mm intervals,[4] such as follows:[2]
