title: Hepatic ultrastructure in congenital syphilis.
abstract: The ultrastructural changes in the liver in a case of congenital syphilis were studied. Treponema organisms were easily demonstrated in 1-micrometer sections stained by toluidine blue, as well as in electron micrographs. Most organisms were extracellular, but some were identified within hepatocytes.
