Janeway Lesions vs. Osler Nodes. Both found in bacterial endocarditis. Osler Nodes: Painful, palpable red lesions usually on fingers/toes. They are caused by immune complexes. (Image Credit) Janeway Lesions; Non-painful, macular lesions, usually on palms/soles. They are caused by septic emboli, more common in Staph aureus endocarditis. (Image ...
Fig 1. Janeway lesions on the sole of the foot (A) and palm of the hand (B). Fig 2. Echocardiogram showing endocarditis vegetation. Janeway lesions are painless, macular, haemorrhagic lesions that occur most commonly on the palmar surface of the hands and feet. These lesions are non-tender, in contrast to the exquisitely painful Osler’s node.
Janeway's lesions and Osler's nodes are regarded as excellent clues to the diagnosis of infectious endocarditis; however, very few physicians have actually witnessed these findings, and there is some confusion in distinguishing between the two. This article concerns a patient with infectious endocarditis due to Diplococcus pneumoniae, who had tender vesicular lesions thought to be Osler's ...
Jul 24, 2023 · Osler nodes and Janeway lesions are cutaneous manifestations of endocarditis, a disease most commonly arising from a bacterial or fungal infection of the cardiac endocardium. Osler nodes are tender, purple-pink nodules with a pale center and an average diameter of 1 to 1.5 mm. They are generally found on the distal fingers and toes, though they ...

Figure 1 shows such a lesion on the pad of the long finger of a young woman with prosthetic valve endocarditis caused by Staphylococcus aureus. Figure 2 shows an example of an Osler’s node in a young man with endocarditis caused by S. aureus. Note the lesion on the pad of the fourth toe and the many petechial hemorrhages on the sole of his foot. Osler’s nodes have an average diameter of 1 to 1
The lesions on the palms and toes were identified as Janeway lesions and Osler's nodes, respectively. Cardiovascular examination revealed a loud S1, mid-diastolic murmur, and a short systolic murmur in the mitral area. Blood investigations showed neutrophilic leukocytosis, anemia, and sterile blood cultures. Brain imaging revealed right middle ...
