	Osler's nodes are painful, red, raised lesions found on the palms of the hands and the soles of the feet. They are named after Sir William Osler, who first described them in the early 20th century. These nodes are considered a classic clinical sign associated with a number of systemic conditions, most notably [[infective endocarditis]]. The appearance of Osler's nodes is due to the deposition of immune complexes in the small vessels of the skin.
