Janeway lesions are non-tender, small erythematous or haemorrhagic macular or nodular lesions on the palms or soles only a few millimeters in diameter that are pathognomonic of infective endocarditis.[1] Pathologically, the lesion is described to be a microabscess of the dermis with marked necrosis and inflammatory infiltrate not involving the epidermis, which is due to the deposition of circulating immune complexes in small blood vessels.[1]
They are named after Edward G. Janeway (1872–1917), a professor of medicine with interests in cardiology and infectious disease.[2]
