Abstract:
Actinic keratoses (AKs) are common skin lesions that are often considered to be precancerous markers for the future development of skin cancers. There are various treatment options, including cryotherapy, imiquimod, 5-fluorouracil, curettage, lasers, and photodynamic therapy (PDT). Laser-assisted drug delivery, using the combination of a fractional ablative laser with PDT, is an effective therapy. Our clinical experience with six patients demonstrates that the combination of fractional ablative 2,940nm erbium:yttrium-aluminum-garnet laser with blue light PDT is safe and effective for the field treatment of AKs.
