Osler nodes are best described as which of the following?

Painful, tender subcutaneous nodules on the finger and toe pads in the setting of infective endocarditis are Osler nodes. They form from immune complex deposition in small vessels, leading to a painful vasculitis of the digit pulp. The tenderness and location on the fleshy parts of the digits help distinguish them from other endocarditis findings. In contrast, non-tender lesions on the palms and soles (Janeway lesions) arise from septic emboli, Roth spots are retinal hemorrhages with white centers, and mycotic aneurysms are vascular dilations from septic infection. So, the description of painful lesions on fleshy portions of the extremities is the best fit.
