Cutaneous vasculitis and vasculopathy

Abstract

Although uncommon to rare in occurrence, cutaneous vasculitides and vasculopathies are becoming better recognized entities in veterinary medicine. The heterogeneity in their clinical presentations can be confusing, and the diagnostic evaluation of suspected cases can be clinically and financially challenging. The most important step is confirming a vasculitic/vasculopathic process histologically and then searching for an underlying cause. As many cases are diagnosed as idiopathic by exclusion, a familiarity with treatment options is important and may be guided in some cases by the histological inflammatory pattern. Because of the frequent temporal association with drug administration, any case of vasculitis requires a thorough drug history and physical examination for systemic complications. Familiarity with breed-associated vasculopathies is also key in properly diagnosing and managing these problems.
