title: Josef Jadassohn (1863-1936), Felix Lewandowsky (1879-1921), and their syndrome.
abstract: Josef Jadassohn (1863-1936) and his assistant, Felix Lewandowsky (1879-1921), were eminent German dermatologists who had several dermatology conditions linked eponymously. One such condition is Jadassohn-Lewandowsky syndrome, which is a type of pachyonychia congenita - a disease that is characterized by severe thickening of the nail due to massive nail hyperkeratosis. This report describes Jadassohn-Lewandowsky syndrome and the men behind this disease.
