Actinic kerastoses is the name given to sun-induced precancerous spots. These spots occur typically in sun exposed areas such as the face, arms, chest and hands. They are usually small flaky spots without substance other than scale. May actinic keratoses will come and go on their own. Some keratoses can sting, itch, or even thicken and ultimately develop into a skin cancer.
Treatments can include: observation or several different removal methods such as prescription creams, photodynamic therapy and liquid nitrogen.
