Janeway lesions and Osler's nodes: a review of histopathologic findings

J Am Acad Dermatol. 1990 Jun;22(6 Pt 1):1088-90. doi: 10.1016/0190-9622(90)70157-d.


The histologic findings in Osler's nodes and Janeway lesions have been reported rarely; we found descriptions of only 10 such cases, mostly from the late nineteenth- and twentieth-century French literature. We found gram-positive coccobacilli in the dermal abscess of a Janeway lesion from a patient with bacterial endocarditis. This finding suggests that septic microemboli are the cause.
