Several predictors for increased AK risk from UV radiation have been identified:.
Actinic reticuloid syndrome is considered the most severe stage of chronic actinic dermatitis CAD.

If a shave biopsy is performed, it should extend through to the level of the dermis in order to provide sufficient tissue for diagnosis; ideally, it would extend to the mid-reticular dermis. Ultraviolet radiation is believed to contribute to the development of actinic keratoses by inducing mutations in epidermal keratinocytes, leading to proliferation of atypical cells.
