Hemorrhages in the fingernail beds in suspected endocarditis are called?

Splinter hemorrhages are tiny streaks of blood that run vertically under the nail plate, giving a brownish to red line in the nail bed. In infective endocarditis, microemboli from vegetations can damage small capillaries in the nail bed, producing these streaks. They’re a classic peripheral sign when endocarditis is suspected, often seen on the fingernails and sometimes the toenails. Other related signs include Osler nodes, which are tender nodules on the finger pulps due to immune complex deposition; Janeway lesions, which are painless hemorrhagic patches on the palms or soles from septic emboli; and Roth spots, retinal hemorrhages with pale centers. The nail-bed hemorrhages specifically describe splinter hemorrhages, helping distinguish them by location and appearance.
