Multiple Bowen's disease on the finger associated with human papillomavirus type 34.

Human papillomavirus (HPV) infection has been suggested as a potential risk factor for Bowen's disease. Here, we report a case of a 40-year-old man with Bowen's disease on the finger showing a discontinuous skip lesion, in which HPV-34 was detected. Our case is a reminder that the possibility of multiple lesions must be considered when Bowen's disease occurs on the finger.
