What is purpura fulminans? It's basically retiform purpura, EVERYWHERE! But what is retiform purpura? It's the sharp angulated purpuric plaque/patch you can see in the skin. When you see retiform purpura, it means there's likely either a vasculitis or vasculopathy causing it!

Why does that happen? (Nerd-alert - this is one of my favorite ah-ha moments from residency) - The skin is perfused in cones, so if you knock them out, you get circles of necrosis. When you combine a bunch, you get the angular appearance! See my terrible MS paint attempt:
