Presence of human papilloma viruses in intraosseous ameloblastoma.
OBJECTIVE
This study investigated the possibility that human papilloma virus (HPV) is a possible etiologic agent in the development of ameloblastoma.


METHODS
DNA was extracted from 18 formalin-fixed, paraffin-embedded biopsy specimens and assayed for the presence of HPV DNA by PCR using the L1 consensus primer and specific primers for HPV types 6/11, 16 and 18.


RESULTS
Eight samples (67%) were positive for HPV. Of the 8 HPV-positive samples, 7 were positive for HPV 18. Four of the HPV 18-positive samples were also positive for HPV 6/11. One HPV-positive sample was not positive for any of the type-specific primers.


CONCLUSIONS
No conclusions can be drawn about the etiologic role of HPV from this study, but surgical manipulation is suggested to be one of the reasons for HPV presence attributable to contamination from the surface mucosal epithelium in these tumors.
