Key Takeaways
Actinic keratoses are a type of skin lesions that are caused by long-term exposure to the sun's UV radiation. They typically appear as irregular plaques or papules on parts of the skin areas exposed to the sun. Actinic keratoses are benign regions, but if left untreated, they can sometimes develop into skin cancer.
