Microscopic evaluation
- Look for cellular expansions, which in the anterior pituitary confers a loss of normal cellular heterogeneity.
- 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.
Incidences of silent pituitary adenomas.[2]
A silent gonadotroph pituitary adenoma which is in this case is eosinophilic (contrary to normal, basophilic, gonadotroph cells).[3]
Microscopy report
In normal autopsy:
Adenohypophysis and neurohypophysis with no focal changes. |
