Abstract
INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease associated with significant morbidity. Although cutaneous squamous cell carcinoma (cSCC) is a rare complication, it has serious consequences, particularly when associated with high-risk human papillomavirus (HPV) infections. This study examines two cases of HPV-16-induced cSCC in patients with long-standing HS and explores the potential role of HPV vaccination in preventing such malignancies. METHODS AND RESULTS: We report on two male patients with severe HS (Hurley stage III) and cutaneous squamous cell carcinoma with positive detection of HPV DNA in the tumour tissue. CONCLUSIONS: HPV vaccination may offer a preventive approach to cSCC in HS patients by reducing high-risk HPV infections. Incorporating vaccination into the management of HS, particularly in high-risk individuals, could potentially reduce the incidence of malignant transformation and improve long-term outcomes. Further research is warranted to validate these findings and refine prevention strategies.
