Osler’s nodes on the dorsum of the foot.įreedberg IM, Eisen AZ, Wolff K, et al, eds.įitzpatrick’s Dermatology in General Medicine.ħth ed. Osler’s nodes and the recognition of infective endocarditis: a lesion of diagnostic importance. 4 It is now believed that microemboli account for Osler nodes and elicit a secondary vasculitis through immune-mediated mechanisms. The pathophysiological origin of Osler nodes remains obscure more than a century after the original description of this entity. 2 Osler nodes sometimes also accompany bacteremia without endocarditis as well as septic endarteritis, typhoid fever, gonococcemia, systemic lupus erythematosus, and nonbacterial thrombotic endocarditis. The nodes can appear on the dorsa of the feet (which this patient reported) and elsewhere. Painful fingers may be the earliest complaint or the chief complaint, 1 as with this patient. Osler nodes are small, usually raised, purplish red lesions, which are always tender, appear suddenly, and last 4 to 5 days. The patient’s functional status improved with long-term antibiotic therapy. Transesophageal echocardiography showed large, highly mobile vegetations on both leaflets of the mitral valve. Blood cultures grew Enterococcus faecalis, and intravenous antibiotic therapy was started. On examination, a purplish red maculopapular lesion was noted on the pulp of her finger and was identified as an Osler node. She also had an unintentional 20-lb weight loss. Findings from an extensive rheumatological workup were negative. During this period, she had been hospitalized twice for the same complaint. 12.For 4 months, a 41-year-old woman had pain in the pulp of her fingers and dorsa of her feet that was associated with transient maculopapular lesions at different sites.MICHAELSONWALSH ER: Osler's Node-a complication of prolonged arterial cannulation N Engl J Med 283:472-473, 1970 Crossref Medline Google Scholar Arch Intern Med 127:296-298, 1971 Crossref Medline Google Scholar PUKLINBALISBENTLEY JGD: Culture of an Osler's node.
