Actinic Keratosis

Actinic Keratosis (Solar Keratosis)

Overview

Actinic keratoses are rough, scaly patches on the skin caused by years of cumulative sun exposure. They are considered precancerous because a small percentage can progress to squamous cell carcinoma if left untreated. Early detection and treatment are important for prevention.

• Flat to slightly raised pink, red, or brown lesions
• Typically found on sun-exposed areas of skin
• May itch, burn, or feel tender to the touch
• Patches may come and go, sometimes recurring in the same spot
• Surrounding skin often shows signs of sun damage

Affected Areas

Face, Scalp, Ears, Forearms, Hands, Neck
