Detection of Human Papillomavirus in Temporal Bone Inverted Papilloma by Polymerase Chain Reaction.

There is debate about the role of human papillomavirus in the induction of rare inverted papillomas involving the temporal bone and in the higher recurrence rates and association with squamous cell carcinoma of temporal bone inverted papillomas compared with sinonasal inverted papillomas. An exhaustive review of the literature revealed that eight cases of temporal bone inverted papilloma have been analysed for human papillomavirus. None of the cases studied with in situ hybridization proved positive. Only one case was found to be positive using the more sensitive polymerase chain reaction assay. We present the first two cases of Schneiderian-type papilloma involving the temporal bone to be analysed by type-specific polymerase chain reaction methods for human papillomavirus.
