Hematoxylin-eosin staining (A), and anti-fibrin immunohistochemistry (B) (overview (scale bar = 100 µm and magnified inlet (scale bar = 10 µm) (n = 19) shows expanded capillaries with fibrinous microthrombi. In a subset of patients focal fresh hemorrhage could be observed (C), Masson’s trichrome staining (overview (scale bar = 100 µm and magnified inlet (scale bar = 10 µm).
