ABSTRACT
The skin is an organ that is well supplied with vasculature and frequently develops manifestations of vasculitis. Often, the skin may be the initial organ affected and, at times, may seem to be the only organ affected (1-3). However, except in some rare disorders, the skin is reflective of a systemic process. The vessels that are affected in the skin are most often small vessels, frequently the postcapillary venule, but vessels of larger size may also be affected. The size of the affected vessel correlates at least in part with the syndrome that affects the patient.
