The nodes are commonly indicative of subacute bacterial endocarditis. [4] 10–25% of endocarditis patients will have Osler's nodes. [5] Other signs of endocarditis include Roth's spots and Janeway lesions. The latter, which also occur on the palms and soles, can be differentiated from Osler's nodes because they are non-tender. [3]
Roth's spots, also known as Litten spots or the Litten sign, [1] are non-specific red lesions with white or pale centres, seen on the retina of the eye and although traditionally associated with infective endocarditis, can occur in a number of other conditions including hypertension, diabetes, collagen vascular disease, extreme hypoxia, leukemia and HIV.
Osler's nodes are thought to be due to immunologic phenomenon where deposition of immune complexes provoke inflammatory response, leading to swelling, redness and pain. On the contrary, Janeway lesions are thought to be due to embolic phenomenon in cutaneous blood vessels of palms and soles which does not cause pain or least pain.

When valvular heart disease results from infectious causes, such as infective endocarditis, an affected person may have a fever and unique signs such as splinter haemorrhages of the nails, Janeway lesions, Osler nodes and Roth spots.
Osler's nodes are raised tender nodules on the pulps of fingertips or toes, suggestive of subacute bacterial endocarditis. Osler described them as "ephemeral spots of a painful nodular erythema, chiefly in the skin of the hands and feet." Osler nodes are usually painful, as opposed to Janeway lesions which are due to emboli and are painless.
