Actinic Keratoses

Actinic keratoses are precancerous, rough scaly skin growths caused by long-term UV exposure that can progress to squamous cell carcinoma if left untreated.

Actinic keratoses (AKs) are precancerous skin growths caused by long-term exposure to ultraviolet (UV) radiation, typically from sunlight or tanning beds. These lesions frequently appear on sun-exposed areas—such as the scalp, face, dorsal hands, and forearms—and are characterized by rough, scaly patches that are often easier to palpate than to see. Because AKs can progress into squamous cell carcinoma (SCC), prompt treatment is recommended. Various therapeutic options are available, including cryotherapy (liquid nitrogen), topical field treatments, and photodynamic therapy (PDT).
