Pathological findings of the resected right ureter (Hematoxylin-eosin stain, ×20) As can be seen, two vessels (A) have thick fibrinoid deposits within their walls (B), sign of necrotic vasculitis. In the periphery, a dense polymorphous inflammatory infiltrate with polynuclear eosinophils (C) can be observed as well as granulomas.
