Actinic keratosis

It takes years of sun exposure to develop actinic keratoses. They typically form in people over the age of 40 but may be seen in younger patients. They occasionally itch but are usually asymptomatic. Early actinic keratosis can resolve spontaneously if protected from light exposure.
