Actinic keratosis is the most common sun-related growth. Usually, these people are fair-skinned, burn easily and tan poorly, as well as have occupations or hobbies that result in excessive sun exposure.
Many people have new actinic keratoses each year.
They may be treated effectively by available methods. Actinic keratoses are found chiefly on the sun-exposed areas of the face, ears, forearms, and dorsum of hands. However, they may occur on any area that is chronically or repeatedly exposed to the sun, such as the back, chest, and legs. They usually appear as multiple discrete, flat or elevated, verrucous, keratotic lesions. With time, actinic keratoses may develop into invasive cutaneous horns or skin cancers.
