single or multiple discrete but poorly demarcated superficial skin lesions. They can be red & most commonly have a gritty sandpaper like feel on the surface.

The treatment is ablation by freezing with liquid nitrogen, topical 5-FU skin chemotherapy, chemical peel, laser or dermabrasion. Dr. Stone has had one removed from the left cheek with a laser & you can’t tell where it was. The best treatment for a specific individual is dependent on the number of actinic keratoses to be ablated & the doctor’s experience.
