Overview

Splinter hemorrhages are small areas of bleeding (hemorrhage) under the fingernails or toenails. Splinter hemorrhages look like thin, red to reddish-brown lines of blood under the nails. They run in the direction of nail growth.

They are named splinter hemorrhages because they look like a splinter under the fingernail.

Pathophysiology

In certain conditions (in particular, infective endocarditis), clots can migrate from the affected heart valve and find their way into various parts of the body. If this happens in the finger, it can cause damage to the capillaries resulting in a splinter hemorrhage.

Associated Conditions

Splinter hemorrhage is a nonspecific finding and can be associated with^[1]^[2]:

Natural History, Complications and Prognosis

Initially splinter hemorrhages are plum-colored, but they then darken to a brown or black color in several days.

Diagnosis

The presence of splinter hemorrhages is not sensitive but is a fairly specific finding the diagnosis of endocarditis. Only one in six patients with endocarditis will have splinter hemorrhages. Therefore the absence of splinter hemorrhages does not exclude endocarditis. If there is a clinical suspicion of endocarditis and splinter hemorrhages are observed, then this is likely a fairly specific finding for endocarditis.

Physical Examination

Physical examination may include special attention to the heart and blood circulation systems.

Laboratory Findings

Electrolyte and Biomarker Studies

Laboratory studies may include:
