title: Actinic cheilitis.
abstract: Ultraviolet (UV) radiation of the vermilion border of the lips can precipitate recurrent herpetic infections, varying degrees of dysplasia, and squamous cell carcinoma. UV light also can aggravate certain systemic conditions, such as lupus erythematosus, and produce solar urticaria, porphyrias, and drug photosensitivity reactions.
