Janeway lesions are rare, non- tender, small erythematous or haemorrhagic macular, papular or nodular lesions on the palms or soles only a few millimeters in diameter that are associated with infective endocarditis and often indistinguishable from Osler's nodes. Janeway lesions are more commonly seen in acute endocarditis, when bacteria such as Staphylococcus aureus may be cultured from them. The histology is usually consistent with septic micro- embolism (i.e.
bacteria may be found within the blood vessels). The pain usually proceeds nodule development, and they disappear in hours to days, leaving no sequelae. Janeway lesions are irregular, non-tender, erythematous, or hemorrhagic macules or papules commonly found on the palm and soles, lasting days to weeks. [4] Janeway lesions are skin patches that develop on the palms and feet.
janeway lesion, They usually last a few days to a few weeks before disappearing. Most cases of the condition indicate infective endocarditis, a heart infection. Sometimes, it can signify other conditions, such as systemic lupus erythematosus (SLE). Janeway lesions are small nontender, erythematous or hemorrhagic macules typically located on the palms and soles; associated with acute infective endocarditis. Unlike Osler nodes (which are tender), Janeway lesions are characteristically painless and blanching.
janeway lesion, To our knowledge, this is the first report of unilateral Osler nodes and Janeway lesions in the lower extremities. Janeway lesions are defined as macular, non-painful, erythematous lesions that occur on the palms and soles, commonly associated with infectious endocarditis and protracted bacteremia. Explore Osler nodes and Janeway lesions, important clinical signs of infective endocarditis. Learn about their characteristics, underlying mechanisms, and implications in the diagnosis and management of this serious infection.

They typically last for days to weeks. They are usually seen with the acute form of bacterial endocarditis. Janeway lesions are named after Theodore Caldwell Janeway (1872–1917), an American professor of medicine.
