Medical Eponyms

Janeway lesion (1899) small painless, palpable, erythematous/haemorrhagic nodular lesions on the palms or soles infrequently associated with infective endocarditis.

In trying to determine whether a given case is more probably due to endocarditis or to another malignant process I have found that attention to the position of the hemorrhages is at times very helpful. Several times I have noted numerous small hemorrhages with slight nodular character in the palms of the hand and soles of the feet, when possibly the arms and legs had but a scanty crop in malignant endocarditis, whereas this has not been my experience with processes likely to be mistaken for it.
