Topical photodynamic therapy is used in the treatment of Bowen's disease (BD). This is a retrospective review of the data of Chinese patients with BD who have undergone photodynamic therapy at the National Skin Centre from March 2006 to March 2010. A total of 43 Chinese patients with 56 histologically confirmed BD were included. The clearance rate at 3 months was 73.2%. Pain was the most common side effect. The clearance rate in our patients is lower than rates cited in current literature. Future prospective studies utilizing topical PDT in the treatment of BD in Asian skin are needed to evaluate its efficacy in Asian patients.
