Infectious Endocarditis Accompanied by Leukocytoclastic Vasculitis

Bacterial endocarditis is a rare infection that can present with variable clinical manifestations. Rarely, it can present as cutaneous vasculitis characterized by a purpuric rash mimicking immune-mediated vasculitis. There have been a few case reports of leukocytoclastic vasculitis (LCV) due to infectious endocarditis. It is important to recognize endocarditis as a potential cause of vasculitis because treatment with immunosuppressive agents can have devastating consequences. We report a case of a 53-year-old male with endocarditis who developed a palpable purpura of the bilateral lower extremities. A skin biopsy was performed, and histopathologic and immunofluorescence studies demonstrated LCV.
