Abstract:
Several papules on the floor of the mouth and the ventral surface of the tongue of a zinc-deficient rabbit were studied by light and electron microscopy. These papules appeared to be consistent with focal epithelial hyperplasia of man and chimpanzees. There was a concurrence of cytoplasmic vacuolization with the appearance of viral particles within the nucleus. Intranuclear crystalline viral aggregates were frequently observed in the upper spinous cells.
