| Differential diagnosis | Marfan syndrome |
Lincoln sign is the medical sign consisting of excessive popliteal artery pulsation due to hemodynamic effects of aortic regurgitation.[1] This sign is associated with Marfan syndrome, in which aortic root dilation and aortic incompetence are common features.
History
The name Lincoln sign is based on a hypothetical diagnosis for a patient, namely the USA's 16th president Abraham Lincoln. In 1962, Dr Abraham M. Gordon suggested that Lincoln had Marfan's syndrome.[2] In 1964, Dr Harold Schwartz adduced further evidence that Lincoln might have had Marfan syndrome.[3] Later, Schwartz suggested that, based upon evidence shown in a famous photograph, Lincoln had the aortic insufficiency associated with what is now called Lincoln sign.[4]
However, Gordon's hypothesis is highly controversial.
