Surgical specimen histopathology from a 72-year-old Italian male patient affected by severe COVID-19: (A) complete thrombosis of the medium-sized splenic artery [hematoxylin and eosin, x2.5 objective]: (B) neutrophils infiltration accompanied by karyorrhexis inside the tunica media and adventitia, a classical picture of “leukocytoclastic vasculitis”, with a still preserved endothelial layer [hematoxylin and eosin, x10 objective]; (C) immunohistochemistry for CD61 reveals platelets interaggregating and adhering to the endothelial cells (black arrows), together with occlusive microthromboses of vasa vasorum (red arrows) [2f2 clone, x10 objective]; (D) the platelets aggregates, adhering tenaciously to the endothelium, contain also blue-stained fibrin (blue arrows) [phosphotungstic acid hematoxylin, x10 objective].
