Leukocytoclastic angiitis in subacute bacterial endocarditis.
The case of a patient who had palpable purpura on his lower extremities due to Lactobacillus-caused subacute bacterial endocarditis is reported. Histologic examination of the purpuric lesions demonstrated a leukocytoclastic angiitis. It is postulated that purpuric and other cutaneous lesions of subacute bacterial endocarditis are related to circulating immune complexes.
