Actinic keratoses (AKs) are subtle, persistent rough spots usually found on sun exposed areas. Gone are the days when these were found only in the elderly. Over the past 15 years, we have been amazed to see how many of our patients in their 30s already exhibit these lesions. If left untreated, these can eventually transform into skin cancers called Bowen’s, basal cell carcinoma or the potentially more aggressive squamous cell carcinoma. As a matter of course, we treat every single one of these lesions rather than adopt a “wait and see” approach.
Treatment may include topicals such as 5-fluorouracil (Efudex) or imiquimod (Aldara) cream as well as Photodynamic Therapy.
