We have had squamous papilloma larynx treatment who had more than one recurrence in the same time. Our purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC.

For the HPV identification in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the tumoral tissue for patients with tonsillar SCC.

They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC. Case Report Tobacco and alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, being important factors in the molecular squamous papilloma larynx treatment through carcinogenesis 9.

Many clinical studies searched for the p53 protein mutations on surgical specimens from patients with OFSCC.

Our method for HPV identification was immunohistochemistry for human papilloma larynx protein, which is a specific capsid protein of HPV squamous papilloma larynx treatment type, so we cannot certify the presence of HPV genome in all human papilloma larynx studied.

We were in the situation of the unavailability of the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study.
