A child had condylomata acuminata localized to the oral cavity. Main points of interest were this exclusive localization, the extremely high number of papillary lesions, not reported in the literature until now, and the excellent response to interferon and local applications of podophyllin. Histologic, ultrastructural, and in situ molecular hybridization techniques were performed to make a correct diagnosis. Transmission of the etiologic agent and therapeutic approaches are discussed.
