Microscopic evaluation

  • Look for cellular expansions
  • If present, distinguish it as hyperplasia or neoplasia. If uncertain, by using reticulin immunohistochemistry, hyperplasia will show a preserved reticulin meshwork, whereas pituitary adenomas have disruption of it.[1]
  • For adenomas, unless otherwise indicated by the medical history, will generally by definition be of the silent type. Basophilic or acidophilic staining may give a clue about the subtype, but immunohistochemistry is generally required.

Microscopy report

In normal autopsy:

Adenohypophysis and neurohypophysis with no focal changes.
