Human papillomavirus in oral verrucal-papillary lesions. A comparative histological, clinical and immunohistochemical study.

The purpose of this study was to determine the presence of Human Papillomavirus (HPV) virions in the verrucal-papillary (OVP) lesions by clinical, histological and immunohistochemical [peroxidase-antiperoxidase (PAP) features]. Thirty seven positive cases were compared with 47 negative cases. Considerable overlapping of clinical and histological features can be seen among all these lesions. The study provides evidence that there are no clinical or histologic features with taken alone are strongly correlated with the presence of virions in oral lesions.
