– Subungual (splinter) hemorrhages: Dark-red, linear lesions in the nail beds
– Osler nodes: Tender subcutaneous nodules usually found on the distal pads of the digits
– Janeway lesions: Non-tender maculae on the palms and soles
– Roth spots: Retinal hemorrhages with small, clear centers; rare

OSLER NODES AND JANEWAY LESIONS
OVERVIEW
• Cutaneous manifestations of bacterial endocarditis. – Also rarely described in systemic lupus erythematosus, gonococcemia, hemolytic
anemia and typhoid fever.
• Osler nodes: red-purple, slightly raised tender nodules often with a pale
center. Average diameter 1 to 1.5mm. – Can occur at any time during the course of endocarditis (usually late in subacute)
• Janeway lesions: non-tender, hemorrhagic
• palms and soles – More commonly see in acute endocarditis
