Methyl-aminolevulinic acid photodynamic therapy for actinic keratoses: a useful treatment or a risk factor? A retrospective study

Abstract

PDT is certainly a good method to treat AKs, but it is important also to consider all its side effects. Among them, the carcinogenetic risk is still underestimated. We suggest that patients with multiple risk factors for NMSC treated with PDT should undergo more frequent follow-ups, in order to prevent malignant progression.
