Treatment of Bowen's disease of the penis with imiquimod 5% cream

Abstract
We present a case of persistent and progressive Bowen's disease (squamous cell carcinoma in situ) of the penis, in an otherwise healthy 56-year-old man. Treatment with imiquimod 5% cream was effective when applied once a day for 3 consecutive days followed by 4 days without treatment, over a period of 5 weeks.
