Summary features (1):
- in the UK, incidence of 5.9-15% of the normal population over the age of 40 years
- male to female ratio of about 2:1
- increased prevalence with age
- there an increased prevalence in areas with high local incident ultraviolet radiation (high altitudes and low latitudes)
- incidence higher in individuals with a fair skin; also increased incidence in individuals with high cumulative lifetime sun exposure
- there is an increased risk of actinic keratoses, and most non-melanoma skin malignancies, in patients receiving immunosuppressive treatment
Note that about 20-70% of solar keratoses regress spontaneously over 1-2 years, but typically 15% recur (2,3).
