Actinic Keratosis are scaling epidermal lesions, which consist of dysplastic keratinocytes. They mostly appear in pale-skinned patients which are chronically overexposed to UV radiation. Actinic keratosis is a precancerous epidermal lesion, which can progress into a squamous cell carcinoma. According to Guenthner et al., 97% of squamous cell carcinomas (a nonmelanoma skin cancer) were associated with a cohesive AK lesion MedDRA version: 8.1 Level: LLT Classification code 10000614 Term: Actinic
