Actinic Keratosis and Treatment MethodsKatherine Parkinson, MD What is an Actinic Keratosis?An Actinic Keratosis (AK) is a precancerous lesion which has the potential to turn into a form of skin cancer called a Squamous Cell Carcinoma (SCC). It is important to be aware that an AK may “flake off” and then seem to disappear for a while only to reappear some time later. However, it is still important to have these lesions assessed by a dermatologist as left untreated, more AKs may form and grow deeper into the skin resulting in the development of skin cancer. Who is at risk to develop AKs?While anyone with repeated sun exposure has the potential to develop an AK, some factors make certain individuals more likely to develop AKs. These factors include:
How is an AK treated?Once you have been clinically diagnosed as having AKs, treatment will be necessary. There are many forms of treatment available including: Photodynamic Therapy (PDT) by Blue LightA topical solution (aminolevulinic acid HCI) is applied to the area, which makes the skin more sensitive to light. After approximately one hour of incubation time, the area is then exposed to the Blue Light. The light activates the solution destroying the AKs. As the skin heals, new, healthy skin appears. PDT via Blue Light is a treatment option that is utilized when a patient has numerous AKs. Common areas to be treated by PDT include those which typically receive the most sun exposure: face, scalp, ears, arms, hands, and neck. While repeat treatments of PDT are usually necessary for optimal results, one of the largest benefits to the patient is that there is very little “down time” while healing; lasting approximately 5–7 days. CryotherapyThis method destroys visible AKs by freezing them with liquid nitrogen. The treated skin often blisters and peels off within 10–14 days. As the skin heals, you may see a small white spot where the AK was. Cryotherapy is more likely to be utilized when patients have a small number of AKs to be treated. Topical TherapiesMedications applied at home for approximately 2–4 weeks. Skin becomes red, swollen, crusted and irritated. Healing time can last up to an additional 2 weeks, after which time healthier skin will be revealed.
