How frequently do you recommend skin exams in patients with multiple AKs?

I generally do complete skin exams on patients with multiple AKs annually, however, areas of involvement are checked more frequently. If there is marked involvement, we recommend field therapy generally with PDT or topical preparations such as 5-fluorouracil with calcipotriene.

If there is a history of frequent progression to squamous cell carcinoma or a history of other skin cancers, complete skin exams are recommended to be done more frequently, even as often as every 3 months in exceptional cases.
