Abstract

Cutaneous small vessel vasculitis (CSVV) or leukocytoclastic vasculitis (LCV) is a group of immune complex mediated vasculitides that affect dermal capillaries or post-capillary venules and classically presents as lower extremity palpable purpura. CSVV can be subdivided by antibody type and clinical features. In patients presenting with signs of LCV and ANCA positivity, clinicopathologic correlation is important in characterizing the type of vasculitis. We report an uncommon case of IgA vasculitis with concurrent ANCA-positivity attributed to bacterial endocarditis.

Keywords: ANCA; IgA vasculitis; endocarditis.
