ABSTRACT
Human papillomavirus (HPV)-related benign papillary epithelial neoplasms are common lesions affecting any region of the oral cavity. This study evaluated the trends in frequency, location, and demographics of these lesions over 20 years in a large biopsy service. Following IRB approval, the archives of UF Oral Pathology Biopsy Service between 1995 and 2015 were queried. Cases diagnosed as squamous papilloma, verruca vulgaris, and condyloma acuminatum were included. Extraoral locations, inconclusive diagnoses, or syndrome-related HPV lesions were excluded. Age, gender, location, clinical presentation, and diagnoses were recorded. Data from one calendar year per 5-year span was assessed including the years 1995, 2000, 2005, 2010, and 2015. A total of 1458 cases were identified over the total 5 calendar years assessed. Papilloma as a percentage of total biopsies per year was as follows: 1995 (2.6%), 2000 (3.3%), 2005 (3.6%), 2010 (4.0%) and 2015 (4.5%), representing a 73% (1.9×) percentage increase. Males (56%) were affected more commonly; however, in patients under 19 years, a female predominance was observed. The overall percentage of lesions in females increased by 30.6% over the time frame. The mean age was 54 years (range 1-93 years) with an increase of 10 years over time. About 1.1% of patients had multifocal lesions and 0.2% had a recurrence. In descending order of frequency, the tongue, soft palate, and mandibular gingiva were most involved. Maxillary gingiva and lower lip were the most common locations in patients under 19. Location varied over time, however, the biggest increase was noted for lesions on the gingiva. Squamous papilloma was the most common histologic variant (93.6%). The incidence of benign HPV-related oral lesions increased substantially over the 2 decades studied. This increase was statistically significant with a p-value <0.00045. Other trends noted included increase in the following: the average age, female involvement, and gingival location. Our results indicate a trend for the overall increase in the prevalence of benign oral HPV lesions in our population.
