Epidemiological study of oral lesions related to human papillomavirus (HPV)

Introduction and Objective: The aim of this study was to evaluate the epidemiological aspects of oral lesions related to human papillomavirus (HPV). Material and methods: The sample was composed of histopathological reports issued and archived by the Oral Pathology Department of the Public Laboratory of Mato Grosso, Brazil, between 2005 and 2013. The information’s were collected from diagnosis requisition sheets and histopathological reports and were related to gender, age, histopathological diagnosis and anatomical localization. The statistical treatment analyzed data through frequency distribution. Results: Two hundred and thirty four reports (3.26%) presented a positive diagnosis for HPV. Among the positive lesions, squamous cell carcinoma was the most prevalent (n = 144, 61.53%) and the lesions occurred mainly between 51 and 60 years (n = 43; 29.86%). Verruga vulgaris were more prevalent in participants aged 41-50 years (n = 4; 23.52%) and the anatomical location in which it was most commonly found was lip (n = 6; 35.29%), while papilloma (n = 17; 23.87%) was more prevalent in participants between 41 and 50 years and in the oral mucosa. Conclusion: There was a high prevalence of oral HPV-related lesions in men and participants between 41 and 50 years. Squamous cell carcinoma was the most diagnosed lesion and the lip was the most affected anatomical region.
