Janeway lesions (on hands and feet) are associated with which systemic condition?
Show answer and explanation
Correct answer: B. Infective endocarditis
✓ B) Infective endocarditis is correct.
Janeway lesions are small, painless, hemorrhagic macules on the palms and soles — embolic/septic phenomena from infective endocarditis (IE). Other IE signs: Osler's nodes (painful, on fingers/toes), Roth spots (retinal hemorrhages), splinter hemorrhages (fingernails), and new heart murmur. Dental significance: patients with previous IE require antibiotic prophylaxis for certain dental procedures. Janeway lesions are non-tender (vs. Osler's nodes which ARE tender).
