Pert. to cells that bind with silver salts, which can then be reduced to produce a brown or black stain.

Extracellular matrix proteins are generally silver positive, resulting in an increase in mesangial argyrophilia (Figures 3 and 4).
The light microscopic findings of this condition are very nonspecific, with an increase in mesangial matrix, which results in enhanced argyrophilia (Figures 8 and 9) and occasional thickening of peripheral capillary walls.
The expanded mesangium displays increased argyrophilia.
26,27) In this condition, silver methenamine stain is most commonly negative, which suggests that the composition of the fibrils determines the degree of argyrophilia.
4,13) A corollary of the above is that in the early stages, it may be difficult to appreciate a decrease in mesangial argyrophilia because of the focal and mild matrix replacement that may be present.
44) The end result is that the normal mesangium is replaced by amyloid, explaining the absence of mesangial argyrophilia in the advanced stages of glomerular amyloidosis.
Based on cytoplasmic argyrophilia and ultrastructural and immunocytochemical findings, McNutt and Bolen theorized that adenomatous tumors illustrate both mucinous and neuroendocrine differentiation.
Argyrophilia can be seen, but argentaffin staining is absent.
Silver impregnations did not demonstrate argyrophilia or argentaffinity.
