Symptoms of an Actinic Keratosis

An actinic keratosis appears as a scaly reddish or tan lesion on the epidermis (or surface layer of the skin). It may manifest as rough or scaly skin, bumps, mottled patterns, or protrusions called cutaneous horns. Actinic keratoses usually appear on the face, including the ears and lips, or on the neck, arms and hands. The lesions may range in size from a pinpoint to several centimeters in diameter and may be yellow, brown, red or violet in color and smooth, wrinkled or furrowed in texture.

Risk Factors for an Actinic Keratosis

Fair-skinned individuals, aged 40 to 50 years of age, are more prone to actinic keratosis. Nonetheless, individuals of any age may develop such lesions, particularly in warm, sunny climates. Teenagers are often diagnosed with the condition. Actinic keratosis is also more likely to occur in individuals who spend lots of time in the sun or who frequent tanning parlors.

Diagnosing Actinic Keratosis

A dermatologist should always be consulted about any suspicious lesion on the skin. Unless such a lesion is immediately identifiable by the physician as benign, a surgical biopsy may be performed to determine whether it is premalignant or cancerous. The biopsy procedure is small and painless and takes place in the doctor’s office. A pathology report will be available in a week or two to determine whether further treatment is necessary.

Treating Actinic Keratosis

Depending on the location and severity of the lesion, an actinic keratosis may be addressed in several ways. The patient and doctor will decide on methodology in consultation. These may include:

• Cryotherapy (freezing)
• Curettage (scraping)
• Application of cream or ointment

Because individuals who have had an actinic keratosis are more likely to have another lesion of this type and are also at greater risk of developing a squamous cell carcinoma, they should always opt to have full body checks with their dermatologist at regular intervals. Patients who have been treated for this condition should also avoid sunlight as much as possible.

When patients are exposed to the sun, they should be careful to wear adequate protection, including sunscreen with an SPF of 30 or higher, protective sunglasses, long sleeves, long pants whenever possible, and wide-brimmed hats. They should also, of course, avoid tanning parlors.
