Emergency management of purpura and vasculitis, including purpura fulminans

Abstract

Purpuric lesions are the clinical expression of the passage of erythrocytes from the vascular compartment to the extravascular one, generally following damage related to permeabilization of the walls of small vessels. At times, they are the only clinical feature; at other times, they are a sign of a more complex morbid process and the expression of a serious condition, as in the systemic vasculitides. © 2017 by Taylor and Francis Group, LLC.
