Cutaneous vasculitides: from clinics to morphology

We are aiming to summarize the main clinical and histopathological correlations of most known vasculitides which involve the small-, and medium-sized vessels of the skin. In general, vasculitides can be classified into three major groups: systemic vasculitis with cutaneous involvement, systemic vasculitis with skin limited appearance and single organ vasculitis. We also highlight the importance on the recognition of the clinicopathologic patterns of the corresponding vasculitides, with special emphasis on the histopathologic features and their underlying pathologies.
