Actinic keratosis

Chapter

Abstract

Actinic keratosis (AK) is a circumscribed cutaneous neoplasm presenting chromosomal abnormalities which occurs primarily on sun-exposed skin surfaces in fair-skinned individuals in the form of horny papules. Currently, Ackerman considers that AK is not a premalignant lesion but a real ‘malignant neoplasm’ from the very beginning. It should be considered a superficial squamous cell carcinoma in the same form, as there are superficial basal cell carcinomas. Some have stated clearly and emphatically their belief that AKs are on continuum and may or may not become malignant. Yantsos proposed a change in nomenclature to refer to AKs as keratinocytic intraepidermal neoplasia (KIN) with three grades of evolution that range from AKs to SCCs.
