Actinic Keratosis Picture

Actinic keratosis is a precancerous skin growth usually caused by sun exposure.

Actinic keratosis occurs most commonly in fair skin, especially
in the elderly and in young individuals with light complexions. The growths occur in
sun-exposed skin areas. The growths begin as flat scaly areas that later develop a hard
wart-like surface.

They are classified as precancerous growths. If left untreated, approximately 10% of
actinic keratosis develop into squamous cell carcinoma.
