The current options in the management of actinic keratosis.

Actinic keratosis is a precursor for squamous cell skin cancer. Hence, it is important to treat. For single actinic keratoses, cryo surgery is recommended. For widespread actinic keratoses, imiquimod, photodynamic therapy (PDT) or 5-FU may be used. ''One-shot'' treatments are advocated as prolonged treatment over several weeks probably diminishes patient compliance. Consequently, cryo surgery for single actinic keratoses and PDT for widespread actinic keratoses should primarily be recommended.
