Solar keratoses and variants
Actinic keratoses are commonly found in the aging Australian population as a consequence of years of cummulative sun exposure. Clinically they are characterised by a local scaly area usually on a red base, which recurs after being removed. Sometimes the scale grows excessively forming a keratin horn. Histologically the central feature of a solar keratosis is disruption, crowding and variation in the size and shape of cells occupying the lower two thirds of the epidermal layer.
