Heterogeneous reactions (A) elicited by intravascular polymer include foreign body giant cell vasculitis (arrow 1), intravascular microabscess formation (arrow 2); intravascular fibrous reaction (arrow 3); and histiocytic response (arrow 4) (magnified in panels B-E, respectively); high-power microscopy further demonstrates lamellated strips of foreign granular material, consistent with polymer [A-F: H&E; G: Congo Red; H: Mucicarmine; H: Masson Trichrome; A: 200X; B-I: 400X].
