Background: Voriconazole and genus beta human papillomavirus (HPV) are independently associated with the development of photo-exposed cutaneous squamous cell carcinoma (SCC) but have not been evaluated concurrently. The objective of this study is to determine the prevalence and type of detectable HPV DNA in voriconazole-associated SCC. Methods: SCCs from immunosuppressed patients, in those with and without voriconazole exposure, were evaluated by PCR analysis for HPV DNA and compared to SCC from non-immunosuppressed patients. An additional expanded PCR analysis of all SCC that developed in the voriconazole group was also performed. Results: HPV DNA was detected by PCR in all groups regardless of the immunosuppression status (80.5%) with beta HPV most prevalent (64.3–78.6%). However, immunosuppressed patients were significantly more likely to be infected by beta HPV types 5, 8, 14, 20, and 21 (P-value 0.014), and represented the majority of beta HPV types found in the voriconazole group. Conclusions: In this retrospective study, beta HPV 5, 8, 14, 20, and 21 were commonly detected in voriconazole-associated SCC. The results indicate a possible role of beta HPV in the pathogenesis of cutaneous SCC in photo-exposed areas. Further studies are needed to establish the role of HPV and voriconazole in the pathogenesis of the lesion.
