ABSTRACT

The aim of the most used treatments of actinic keratoses (AKs) is to avoid the conversion into invasive squamous cell carcinoma through the destruction of the lesion; a lot of therapeutic modalities (imiquimod, 5-fluorouracil, electrosurgery with curettage, cryosurgery) are effective and safe in this field, but not many can do it with excellent cosmetic results like treatment with photodynamic therapy (PDT). We have treated with this technique an old patient, whose AK was resistant to other treatments; the most interesting feature of our case comes from the esthetic effects of the PDT employing a methyl-ester of 5-aminolevulinic acid as topical photosensitizer. This kind of therapy has removed not only the lesion but also the photoaging manifestations like the wrinkles and the ugly lines, leaving a smooth skin, as we have proved with 3D-profilometry technique.
