Excellent cosmetic result of daylight photodynamic therapy for facial flat warts in a child.

FFW are among the most frequent infectious skin conditions. Although several pharmacological and physical topical treatments are available, results are often unsatisfactory in terms of efficacy (frequent recurrence) and cosmetic outcome (risk of scars, hyper- or hypopigmentation). We describe the case of multiple recalcitrant facial flat warts treated by daylight photodynamic therapy (DL-PDT) in an otherwise health 8-year-old female child, with complete clearance and excellent cosmetic result. The advantages of DL-PDT over conventional PDT in terms of tolerability, time and cost, especially in paediatric setting are discussed.
