Background and Design: Actinic (solar) keratosis (AK) is a precancerous, epidermal lesion, which develops in sensitive skin exposed to sun for a long period. AKs are divided into different histopathological subtypes. There is a link between the clinical progression of the histopathological subtypes, the degree of cellular atypia, and the precancerous nature of the lesion. Different series have reported that the rate of transformation of AK to squamous cell carcinoma (SCC) ranges between 12% and 20%.
