Actinic keratoses (AK), also known as solar or senile keratoses, are scaly cutaneous lesions that arise from a cumulative effect of sun exposure. These lesions appear as rough, scaly, erythematous papules or plaques that occur on exposed skin surfaces (eg, face, hands, ears, neck scalp, legs, and sometimes thorax). They are typically seen in fair-skinned individuals with a history of chronic sun exposure.
