Abstract: Background: Cutaneous beta human papillomavirus (HPV) infection across cutaneous and mucosal tissues within individuals has not been examined. Methods: A subcohort of men (n = 87) participating in the HPV Infection in Men (HIM) study provided eyebrow hairs, forearm skin swabs, genital skin swabs, oral rinse samples, and anal swabs. Beta-HPV DNA in the 5 tissues was detected using a multiplex assay, and site-specific beta-HPV prevalence was examined. Results: Any beta-HPV was most prevalent in genital skin (81.6%), followed by forearm skin (64.4%), eyebrow hairs (60.9%), oral mucosa (35.6%), and anal mucosa (33.3%). Most prevalent beta-HPV types included HPV-38 (beta-2) in both genital skin (32.2%) and eyebrow hairs (16.1%), HPV-12 (beta-1) in forearm skin (23%) and oral mucosa (9.2%), and HPV-76 (beta-3) in anal mucosa (14.9%). Concordance of any beta-HPV infection was greater (31.0%) across the 3 keratinized tissue sites (genital skin, eyebrow hairs, forearm skin) than across the 2 mucosal sites (anal and oral mucosa, 6.9%). Conclusions: Prevalence of beta-HPV varied by anatomic site of infection. Biological properties of beta-HPV types detected at mucosal sites and their role in disease pathogenesis should be examined.
