Figure 2. Congo red stain confirming the presence of a nodular, tumor-like deposit of amyloid (amyloidoma). The glassy extracellular material brightly stains with Congo red: it is intimately admixed with the lymphoplasmacytic population (A: ×100) and also thickens the vessel walls (C: ×100). The typical apple-green birefringence under polarized light confirms this is amyloid (B, D: ×100).
