A 55-year-old man comes to the office for evaluation of scaliness and redness over his forehead for the past few months. It sometimes causes a stinging sensation on the affected area. Review of systems is noncontributory. He has been working as a lifeguard at the beach for the past 25 years. Past medical history is significant for type 2 diabetes mellitus that is well-controlled with metformin. Temperature is 37.0°C (98.6°F), pulse is 78/min, respirations are 16/min, and blood pressure is 126/75 mmHg. Physical examination reveals a sandpaper-like texture of the forehead on palpation. An image of the lesion is shown below:

Summary
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.
