Cyanosis and pallor can be noted in the tips of the digits in both central and peripheral cyanosis. Severe jaundice may be visible in the palms and soles, especially in small infants.

Clubbing of digits may be noted in cyanotic heart diseases as well many other non cardiac conditions. In clubbing, initially there is fluctuation of nail bed (Grade 1) followed by obliteration of angle between nail and adjacent skin fold (Lovibond angle – Grade 2). Later there is curvature of the nails (parrot beaking – Grade 3). Grade 4 or hypertrophic osteoarthropathy is not common in cardiovascular causes of clubbing, hence the term hypertrophic pulmonary osteoarthropathy. It is a triad of triad of periostitis, digital clubbing and painful arthropathy of the large joints, classical of lung cancer.
Osler’s nodes are tender reddish spots on the distal aspects of the fingers and toes, noted in infective endocarditis.
Janeway lesions are nontender erythematous patches on the palms and soles, seen in in infective endocarditis.
Heberden’s nodes are bony outgrowths from the margin of the distal interphalangeal joints, a feature of osteoarthritis.
Splinter hemorrhages are linear streaks in the nail bed, typically seen in infective endocarditis, though it can also occur with trauma.
Dupuytren’s contracture which affects the ring and little finger may be associated with cirrhosis of the liver, though it can occur without cirrhosis as well.
