Intravascular platelet aggregates and perivascular fibrinogen staining. Representative CD61 immunohistochemistry images (A–F) highlight intravascular aggregates of platelets in a non-Delta/Non-Omicron variant patient (A, B, Patient 4), a Delta variant patient (C, D, Patient 10), and an Omicron variant patient (E, F, Patient 20). Representative fibrinogen immunohistochemistry images (G–L) highlight perivascular staining in a non-Delta/Non-Omicron variant patient (G, H, Patient 4), a Delta variant patient (I, J, Patient 10), and an Omicron variant patient (K, L, Patient 20). Images A–F taken with 40× objective, and images G–L taken with 10× objective.
