Successful treatment for multiple Bowen's disease using photodynamic therapy: A case report.

Bowen's disease, also named squamous cell carcinoma in situ, is usually treated by surgical excision. However, surgery is not suitable to patients with large area of lesions, multiple lesions or in cosmetically important areas where a scar will be visible. Photodynamic therapy (PDT) has advantages of efficacy, safety, and does not generally induce scar or damage to joint function. It could also be used repeatedly. Therefore, PDT might be recommended to treat multiple Bowen's disease. This report shared a case of a patient having suffered from multiple Bowen's disease successfully treated by PDT. PDT not only avoided scars and joint dysfunction, but also raised quality of the patient's daily life.
