What do Osler nodes look like?
Osler nodes are red-purple, slightly raised, tender lumps, often with a pale centre. Pain often precedes the development of the visible lesion by up to 24 hours. They are typically found on the fingers and/or toes.
What are Osler nodes indicative of?
Osler’s nodes result from the deposition of immune complexes. The resulting inflammatory response leads to swelling, redness, and pain that characterize these lesions. The nodes are commonly indicative of subacute bacterial endocarditis.
What are Janeway lesions indicative of?
Janeway lesions are irregular, nontender hemorrhagic macules located on the palms, soles, thenar and hypothenar eminences of the hands, and plantar surfaces of the toes. They typically last for days to weeks. They are usually seen with the acute form of bacterial endocarditis.
Are Janeway lesions cutaneous or subcutaneous?
Janeway lesions (see later description) are caused by septic emboli and reveal subcutaneous abscesses on histologic examination.
What does a Janeway lesion look like?
Janeway lesions are seen in people with acute bacterial endocarditis. They appear as flat, painless, red to bluish-red spots on the palms and soles.
What are Osler nodes and Janeway lesions?
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.[1] Osler nodes are tender, purple-pink nodules with a pale center and an average diameter of 1 to 1.5 mm.[2] They are generally found on the …
Are Janeway lesions transient?
The lesions are usually transient and clear in 1 to 2 days. Similar lesions may also occur in acute endocarditis (e.g., secondary to S. aureus).
What are the Jones criteria?
The original Jones Criteria as proposed by Dr. T. Duckett Jones have been modified four times and the updated revised criteria were published in 1992. According to this latest publication major manifestations are carditis, polyarthritis, chorea, erythema marginatum and subcutaneous nodules.
What are Roth spots?
Roth Spots are defined as a white centered retinal hemorrhage and are associated with multiple systemic illnesses, most commonly bacterial endocarditis.

What’s the difference between Osler nodes and Janeway lesions?
In contrast to Osler nodes, Janeway lesions are non-tender, often haemorrhagic (bleeding into the skin), and occur mostly on the palms and soles on the thenar and hypothenar eminences (at the base of the thumb and little finger respectively). They tend to last days to weeks before healing totally.
Where are the Osler nodes on the hand?
Osler nodes are tender, purple-pink nodules with a pale center and an average diameter of 1 to 1.5 mm.[2] They are generally found on the distal fingers and toes, though they can also present on the lateral digits, hypothenar, and thenar muscles.[3]
How long does it take for Osler nodes to develop?
Osler nodes are red-purple, slightly raised, tender lumps, often with a pale centre. Pain often precedes the development of the visible lesion by up to 24 hours. They are typically found on the fingers and/or toes. They can occur at any time during the course of endocarditis (usually subacute) and last from hours to several days.
What are the symptoms of an Osler node haemorrhage?
The symptoms may include fever, lethargy, shortness of breath, chest pain or palpitations. These symptoms require prompt assessment and investigation by a physician. Splinter haemorrhage in the proximal nail plate is also a sign of bacterial endocarditis. Osler nodes are red-purple, slightly raised, tender lumps, often with a pale centre.
