A2 - Ratner, Désirée PY - 2015 T2 - Procedural Dermatology AB - Photodynamic therapy (PDT) is increasingly used in both USA and Europe for the treatment of actinic keratosis (AK) and selected cases of nonmelanoma skin cancer (NMSC). Being a minimally invasive therapy, PDT is especially suitable for the treatment of multiple lesions, field cancerization and lesions located in areas where optimal cosmetic outcome is essential.1,2 The principle of PDT involves the combination of a photosensitizer, oxygen, and light to produce selective cytotoxic damage of dysplastic cells. In dermatology, PDT is used with a topically applied photosensitizer, which allows for specific lesion targeting.
