초록
Actinic keratosis (AK) is a common, sun-induced, premalignant lesion with a strong likelihood of progressing to a malignancy. The reported risk of AK progressing to squamous cell carcinoma (SCC) varies from less than 1% to 20%. Clinically, induration, pain, large size, marked hyperkeratosis, ulceration, bleeding, rapid growth, and recurrence or persistence may be markers of AK progression into SCC. The risk of SCC metastasizing ranges between 0.5% and 3%. However, SCC of the lip arising from actinic cheilitis is more prone to metastasis than cutaneous SCC,with rates of the former varying between 3% and 20%. Here we report a typical case of SCC from actinic cheilitis with metastasis to the lymph nodes during a 4-year follow-up period. To exclude SCC, we emphasize the need for regular follow-up and prompt evaluation, including careful pathologic examination for actinic cheilitis. (Ann Dermatol 23(1)101∼103, 2011)
