Actinic Keratosis
Actinic Keratoses represent ultraviolet-induced epidermal atypia manifesting as coarse, keratotic macules or plaques on chronically sun-damaged skin. They preferentially affect the face, ears, scalp, and dorsal extremities, though may occasionally extend to the eyelids or periocular region. Their prevalence rises with advancing age and accumulated photodamage and is notably amplified in immunosuppressed populations.These lesions are considered premalignant as they can evolve into squamous cell carcinoma.
