RE: [Histonet] Differentiating between carcinoid & other neuroendocrine tumours

From:"Shelkowsky, Ben"

The Fontana-Masson silver stain for argentaffin is easy but you must pay attention to the details. Refer to TROUBLESHOOTING HISTOLOGY STAINS by Horobin/Bancroft.

	We're trying to differentiate between a carcinoid tumour and other
	neuroendocrine tumours. Grimelius, chromogranin & synaptophysin are positive
	and we need to be more specific as to the type of tumour, with very little
	tissue left in the block! I've been told staining for argentaffin granules
	would be best, but does anyone know which method is the best to go for?
	Thanks, in advance, for your help.
