title: Ultrastructural studies of intraoral verruca vulgaris.
abstract: The literature offers conflicting views regarding the existence of verruca vulgaris in the oral cavity. In an attempt to clarify this issue, a series of ten oral lesions which had been diagnosed as verruca vulgaris and ten oral lesions diagnosed as squamous-cell papilloma were examined ultrastructurally. Six of the lesions diagnosed as verruca vulgaris contained the characteristic intranuclear viral particles which are normally found in that lesion. None of the lesions diagnosed as squamous-cell papilloma exhibited this type of intranuclear viral inclusions.
