RE: [Histonet] Revealing lymph nodes

From:"Marshall Terry Dr, Consultant Histopathologist"

All this time on histonet, I never recall reading the imperative of using Davidson's only as a primary fixative.
So, I was not holding my feet right.

Now let's see, how can we organise separate fixative for breast and colon specimens?
Nah, impossible - forget it.

Terry Marshall notes having had no success with revealing lymph nodes by post-fixation in Davidson's fixative.
Neither have I. The clearing fixative must be used as the initial fixative. 
An old method is to pass the formalin-fixed tissue through alcohols into xylene (or cedar oil). I've never used this method, and the one time I've seen it used it didn't work. 
Once in a while there are no more than three lymph nodes in the axillary contents from a breast cancer. Your surgeon should live with it.
