Actinic keratoses (AKs) are common lesions of the skin’s epidermis (outermost layer) and are caused by long-term exposure to sunlight. They are common in fair-skinned adults.
Signs & Symptoms: Actinic keratosis is the earliest stage in the development of a skin cancer called squamous cell carcinoma (SCC). The typical AK lesion is a dry, scaly, or ‘sand-papery’ and rough whitish, skin-colored or reddish-brown "bump" on the skin. Sometimes the skin cells making up an AK lesion undergo abnormal growth and become a "cutaneous horn."
AKs can be prevented by sun protection and protective clothing. They can be treated with topical chemotherapy, cryosurgery with liquid nitrogen, surgical removal/biopsy, or photodynamic therapy.
