Diagnosis

Actinic keratosis (AK), also known as solar keratosis, is a rough, scaly patch on the skin resulting from prolonged exposure to ultraviolet (UV) radiation. These lesions commonly appear on sun-exposed areas such as the face, lips, ears, forearms, scalp, neck, and back of the hands. AK is considered a precancerous condition as it can potentially progress to squamous cell carcinoma (SCC) if left untreated.
