  https://dermnetnz.org/topics/actinic-keratosis

  Actinic keratosis is a precancerous scaly spot found on sun-damaged skin, also known as solar keratosis. It may be considered an early form of cutaneous squamous cell carcinoma (a keratinocyte cancer). […] Actinic keratoses are usually removed because they are unsightly or uncomfortable, or because of the risk that skin cancer may develop in them. […] Tender, thickened, ulcerated, or enlarging actinic keratoses should be treated aggressively. Asymptomatic flat keratoses may not require active treatment but should be kept under observation. […] Actinic keratoses are prevented by strict sun protection. If already present, actinic keratoses may improve with a very high sun protection factor (50+) broad-spectrum sunscreen applied at least daily to affected areas, year-round. […] Patients who have been treated for actinic keratoses are at risk of developing new keratoses. They are also at increased risk of other skin cancers, especially intraepidermal squamous cell carcinoma, invasive cutaneous squamous cell carcinoma, basal cell carcinoma and melanoma.

  https://puredermnola.com/actinic-keratoses/

  Actinic keratoses (AKs) are precancerous skin growths. They are sometimes referred to as solar keratoses because sun (solar) exposure is a major risk factor for developing them. Patients often incorrectly self-diagnose them as dry skin that “comes and goes.” AKs appear as a rough, red, scaly patch, bump, or horn on the skin. AKs are commonly found on body areas that are exposed frequently to sun (face, scalp, ears, nose, neck, arms, back of hands, lower legs). AKs are often felt before they are able to be seen. These spots may not have visible symptoms, but often have a burning, sensitive, or painful sensation when touched. Approximately 10% of AKs develop into squamous cell carcinoma (SCC), the second most common form of skin cancer. […] Actinic keratosis is directly related to one’s lifetime exposure to the sun or UV radiation. Men are more likely to develop AKs. Actinic keratosis usually present in ages 50 and beyond, but it is not unusual for someone in their 20s or 30s to develop AKs if they have a history of heavy cumulative sun or UV exposure or multiple intermittent sunburns.

  A scaly and rough patch of skin caused by years of sun damage. Treatments include freezing therapy and various topical creams and gels as well as light therapy. Actinic keratosis is an abnormal growth of cells caused by long-term damage from the sun, he says. Because we dont know which ones will become cancer and which will not, dermatologists recommend treatment of these lesions, Dr. Christensen says. Actinic keratoses are often referred to in the plural form because people rarely develop just one. The small bumps typically appear on the parts of the body that are most exposed to the sun’s rays such as the ears, nose, cheeks, temples and bald scalp. They can also appear on the forearms and backs of hands and usually look like rough bumps or patches on the skin. Patients will often notice a rough spot that isn’t going away and ask their dermatologist to take a look at it. Most of the time, the doctor can make a visual diagnosis, and in the cases that are less obvious, will do a biopsy. There are several ways to treat AK, including: Topical destruction: AK primarily affects the top layer of the skin, so when the patient has only one or a few isolated growths, the dermatologist will usually destroy that area of the skin. The most common way to do this freezing therapy with liquid nitrogen, which is either sprayed on the growth or applied with a cotton applicator. This causes a kind of localized frostbite, and the spot will sting for a few minutes. Within a day or two, the spot will develop a crust or small blister, which will fall off and heal within four to six weeks.

  Topical treatments: When there are multiple lesions (for example, on the scalps of bald men who spend a lot of time in the sun without wearing a hat), the use of liquid nitrogen doesnt make sense. Actinic keratoses can be thought of like weeds in a garden, says Dr. Christensen. When you have many of them, it doesnt make sense to just remove them all individually. It is much more effective to apply a field treatment over a broad area, he says. This removes the spots that are visible and also prevents new ones from growing. […] Fluorouracil: The most commonly prescribed cream is fluorouracil, also known as 5-FU (brand name S Efudex, Carac, or Tolak). It works by blocking the growth of abnormal cells that cause the skin condition. […] Imiquimod: This is a type of topical immunotherapy that helps the patient’s immune system to fight off the pre-cancerous lesions.

  Medical therapy has the advantage of being able to treat large areas with many lesions. […] The disadvantages of medical therapies include lengthy courses of treatment with irritation and discomfort. […] The most popular formulation is the 5% cream, which is applied twice daily for 1 month. […] During the treatment phase, the lesions become increasingly erythematous and cause discomfort; in addition, small subclinical lesions become visible. […] This treatment can be temporarily disfiguring, with erythematous ulcerations and crust formation. […] Imiquimod is a topical medication that up-regulates a variety of cytokines, which in turn invoke a nonspecific immune response (interferons, natural killer cells) and a specific immune response (T cells). […] Reaction to the drug is idiosyncratic, with some patients barely reacting and others developing marked inflammation.

  Topical diclofenac sodium 3% gel is a nonsteroidal anti-inflammatory drug approved by the FDA for the treatment of actinic keratosis. […] Its mechanism of action against actinic keratoses is unknown. […] The chief advantage of diclofenac is that it produces little to no inflammation and thus is very well tolerated. […] The goal of surgical therapy is complete eradication of actinic keratoses, usually by physical destruction, with limited to no damage to surrounding healthy tissue. […] Cryosurgery refers to use of a cryogen to lower the temperature of the skin and produce cell death. […] The development of these lesions is directly proportional to sun exposure. […] Actinic keratoses can be reduced or delayed by using sunscreens and reducing sun exposure. […] If the lesions do not respond to topical therapy, they can be treated with cryotherapy with liquid nitrogen spray for 5-20 seconds. […] Lesions become irritated and ulcerate, and eventually are sloughed from healthy skin.
