病毒感染 (Viral infections)
由 HPV 引起的病灶，例如尋常疣 (verruca vulgaris) 與尖型濕疣 (condylomata acuminata) 相當常見 (Fig. 19.38)。扁平疣 (plane warts) 與類疣狀表皮發育不良 (epidermodysplasia verruciformis-like) 病灶可見於感染 HIV 的兒童與青少年。1–3
HPV 相關的子宮頸、外陰、肛門、陰莖原位癌 (carcinoma in situ) 以及侵襲性鱗狀細胞癌 (invasive squamous cell carcinomas) 是一項重要且具有疫苗可預防潛力 (potentially vaccine-preventable) 的問題。4–6
