Which skin finding can be seen in a patient with infective endocarditis?

The dermatological examination in patients with suspected infective endocarditis may prove very useful, as it might reveal suggestive abnormalities of this disease, such as Osler’s nodes and Janeway lesions. Osler’s nodes are painful, purple nodular lesions, usually found on the tips of fingers and toes.

Why does endocarditis cause Janeway lesions?

They are commonly seen in acute endocarditis. Pathologically, the lesion is a microabscess of the dermis with thrombosis of small vessels without vasculitis. They are caused by septic emboli that deposit bacteria leading to formation of microabscesses.

Why is petechiae seen in infective endocarditis?

Conjunctival petechiae, Osler’s nodes, and splinter hemorrhages represent vascular phenomena caused by endovascular infection, most commonly acute infective endocarditis. These findings can also rarely be seen in other endovascular infections such as aortic graft infections (2).

How is bacterial endocarditis diagnosed?

How is bacterial endocarditis diagnosed?

1. Echocardiogram to view the valves and blood flow through your heart.
2. Transesophageal echocardiogram for more detailed view of the heart from the esophagus.
3. Blood tests and cultures to check for bacteria and signs of inflammation.

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.

Can endocarditis cause rashes?

Symptoms and Causes Sweats or chills, particularly night sweats. Skin rash. Pain, tenderness, redness or swelling.

What does Janeway lesions 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 do Osler’s nodes look like?

How is infective endocarditis diagnosed?

If your doctor suspects infective endocarditis, your blood will be tested for bacteria. A complete blood count (CBC) may also be used to check for anemia. A shortage of red blood cells can occur with infective endocarditis. Your doctor may order an echocardiogram, or an ultrasound of the heart.

What are the most common skin manifestations of infective endocarditis (IE)?

In addition to Osler’s nodes and Janeway lesions, cutaneous purpura is another most common skin manifestation of IE, but it is often misdiagnosed as a vasculitic rash of other etiologies.

What are the symptoms of bacterial endocarditis?

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.

What are Janeway lesions of infective endocarditis?

Janeway lesions are erythematous macules that usually affect palms of hands and soles of feet. They are generally painless. Dermatologic examinations have been found to be very important diagnostic methods in the presumptive diagnosis of infective endocarditis.

What are Osler nodes and Janeway lesions in endocarditis?

Osler nodes and Janeway lesions are two rare but well-known skin manifestations of bacterial endocarditis. They have also rarely been described in systemic lupus erythematosus (SLE), gonococcaemia (gonorrhoea), haemolytic anaemia and typhoid fever. They are important as they may help in the earlier diagnosis of a serious medical disorder.
