I was surprised that oral human papillomavirus (HPV) was not included in the discussion, “Oral pathology for the primary-care clinician” (April 2010). I see it fairly often, and dentists with whom I consult comment on the increased incidence in oral HPV lesions, which can lead to the development of oral cancers.—Sharon Martens, ARNP, FNP, Seattle

You are correct. More and more frequently, HPV is being found in the oral cavity. I plan on addressing this topic in a future feature for The Clinical Advisor.—Adam Weiss, DDS (140-12)
