Published in 2024 at "Journal of the European Academy of Dermatology and Venereology"

DOI: 10.1111/jdv.20527

Abstract: Conventional photodynamic therapy (cPDT) is an effective treatment option for field cancerization and multiple actinic keratoses (AK). The main side effect of cPDT is pain during illumination which in severe cases might necessitate early termination… read more here.
