However, HCV infection did not have a significant impact on the overall survival or event-free survival of DLBCL patients [31].HPV infection developing in this site might be due to low immunity from B cell lymphoma or HPV contributing to the development of lymphoma. Primary non-Hodgkin lymphoma of the tongue base: the clinicopathology of seven cases and evaluation of HPV and EBV status. This procedure was carried out under general anesthetic in the form of a modified adenotonsillectomy, using a Boyle Davis gag for exposure and a combination of monopolar cautery for the palatine tonsils and suction cautery for subtotal ablation of the lingual tonsils. https://doi.org/10.1016/j.ijom.2004.08.009.
