Why not.

This seems an ingenious way of detecting argyrophil cells only.
This would be an interesting project. Stain various endocrine containing
cells and other silver attracting substances (eg lipofuscin & melanin)
with the two techniques and compare the results. Also include several
argentaffinomas and argyrophilic tumours.

Subject: [Histonet] argentaffin vs argyrophil



   When  performing  an  argyrophil  stain (Grimelius) one must also per
form  an  argentaffin  stain (Fontana-Masson) to rule out the positive
   argenta=ffin  staining in the Grimelius procedure.  Would it work if
   you  perfor=med a Grimelius on two slides, but left out the reducing
   substance for one =f the slides?

   Thank you,

   Jennifer MacDonald
