<prompt> Tonsillar carcinoma is associated with infection of:HIVHPVHSVNone of the above  <response>: HPV is an epitheliotropic virus that has been detected to varying degrees within samples of oral cavity squamous cell carcinoma.

Approximately 40 of tonsillar carcinomas demonstrate evidence of HPV types 16 and 18. Ref: Schwazs principle of surgery 9th edition, chapter 18.
