Human papillomavirus types in non-cervical high-grade intraepithelial neoplasias and invasive carcinomas from San Luis Potosí, Mexico: a retrospective cross-sectional study.

Background: Viral infections and the burden of high-grade intraepithelial neoplasias (HIN) and invasive carcinomas (IC) associated to infections by human papillomavirus (HPV) types may be prevented by type-specific anti-HPV vaccines. This study determined the prevalence of HPV types in non-cervical HIN and IC diagnosed from 1999 to 2011 at a general hospital in San Luis Potosí, Mexico.

Methods: Review of the 67 formaldehyde-fixed paraffin-embedded non-cervical specimens initially diagnosed as HIN (n = 28) or IC (n = 39) confirmed the presence of tumor tissue in 63 of them and changed the diagnosis of 24 from HIN to low-grade intraepithelial neoplasias, that were excluded from the study.
