Actinic keratosis is a spot on the top layer of skin that generally develops in adults and is pre-cancerous. Like many changes in the skin that occur over our lives, sunlight exposure causes these spots. Over time, the photons of ultraviolet (UV) light trigger enough damage to the DNA of skin cells that the skin starts to grow more rapidly than they should.
In the case of actinic keratosis, what we typically see are red patches of skin that are scaly and rough. To some people, these seem to be dry skin. But as opposed to dry skin which goes away with moisturizer, actinic keratosis may improve and be less scaly with moisturizing, but they never completely go away. As soon as the moisturizer is discontinued, the rough skin builds up again. In some cases, there may be so much thickened skin over these spots, that a very thick mound of skin like a horn develops.
Actinic Keratosis Causes
Because the spots are caused by long-term exposure to ultraviolet light, especially from sunlight, they most commonly occur in our areas of skin that get the most sun. The face, neck, and scalp are the most common areas for actinic keratosis to develop. Next, they may be seen on the backs of hands and fingers as well as the forearms and legs. Less commonly they can occur in other areas including the torso. Some patients will have a solitary spot of actinic keratosis, whereas others may have dozens and dozens of spots. The fairer your skin and the more sun exposure you’ve had over time, the more spots we tend to see. They also become more frequent with advancing age. Yet, they can start to develop and some people as young as the late 20s or early 30s
Actinic keratosis spots may eventually turn into full-blown skin cancer, known as squamous cell carcinoma. Most of the spots will never do this, however, it does occur with enough frequency that it is considered medically necessary to treat actinic keratoses.
There is good news! Actinic keratosis spots are actually very easy to treat. The best dermatologists have extensive experience using liquid nitrogen to treat them. Most commonly the liquid nitrogen is delivered directly to the area. The treatment is delivered in a pulse-like fashion using a liquid nitrogen dispensing gun known as a Cryac gun. If extensive or very large, actinic keratoses may be treated with other options. One of the most frequent options is the use of topical (applied) chemotherapy creams. 5-fluorouracil (Efudex, Carac) is the most frequent topical applied chemotherapy agent used.
