These two cases can be added to the other 15 cases of HPV-positive primary oropharyngeal SCC identified in our department from 1956 to 1969. When determining the incidence of HPV-positive oropharyngeal SCC before the 1970s, a correction factor of about +13% (2/15) accounting for modern pathologic workup of SCCUP during the last couple of decades may be appropriate.
