Osler’s nodes in the toes or fingers
These are similar to petechial spots because they are often red, and they are caused by the same immune complexes with agglutinating properties. However, Osler’s nodes are typically raised lesions found in the body, and they are usually larger than petechial lesions. They are caused by immune complexes that deposit and trigger inflammatory responses in the skin, generally in the palm of the hand and the sole of the feet. They are also found in systemic lupus erythematosus, but evaluating them may be very useful to diagnose infective endocarditis.
