Human Papillomavirus Type 16 in Bowenoid Papulosis, Intraoral Papillomas, and Squamous Cell Carcinoma of the Tongue

Abstract

A 33-year-old immunosuppressed man developed bowenoid papulosis on his genitalia, velvety papules and plaques in his mouth, and invasive squamous cell carcinoma of his tongue. All three lesions were positive for human papillomavirus type 16 (HPV-16). The case provides further circumstantial evidence for a role of HPV-16 in epithelial neoplasia. The possible roles of a second HPV infection and of immunosuppression are also discussed.
