The utility of Osler's nodes in the diagnosis of infective endocarditis.
The etiology of Osler's nodes remains controversial. We describe a patient with endocarditis in whom Streptococcus sanguis was grown from the biopsy of such a lesion. Bacterial embolic events are likely to be the major pathogenetic event in the development of Osler's nodes, and recognition of the etiology of infective endocarditis may be found through biopsy of them.
