Photodynamic Therapy Activated by Intense Pulsed Light in the Treatment of Nonmelanoma Skin Cancer.

Photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) or methyl aminolevulinate (MAL) has proven to be a highly effective conservative method for the treatment of actinic keratosis (AK), Bowen's disease (BD), and superficial basal cell carcinoma (sBCC). PDT is traditionally performed in association with broad-spectrum continuous-wave light sources, such as red or blue light. Recently, intense pulsed light (IPL) devices have been investigated as an alternative light source for PDT in the treatment of nonmelanoma skin cancers (NMSC). We herein report our observational findings in a cohort of patients with a diagnosis of AK, sBCC, and BD that is treated with MAL-PDT using IPL, as well as we review published data on the use of IPL-PDT in NMSC.
