title: Tretinoin therapy for precancerous skin.
abstract: Although few actinic keratoses eventuate as squamous cell carcinomas, these precancerous lesions cannot be ignored. A medical regimen of topical tretinoin use and sun protection appears to be effective in treating and preventing these precancers, with the added cosmetic benefits of ameliorating the alterations which accompany sun damage on exposed skin.
