Retiform purpura is the result of total vascular blockage and damage to the skin's blood vessels. The skin then shows lesions, appearing due to intravascular issues where clots, proteins, or emboli block skin vessels. They can also result from direct harm to the vessel walls, as seen in conditions like vasculitis, calciphylaxis, and certain severe opportunistic infections.
