“Sailor’s Lip,” or actinic cheilitis (AC), is a precursor of squamous cell carcinoma (SCC) found on the lips. Similar to actinic keratosis, actinic cheilitis is a premalignant lesion caused by chronic sun exposure. It is most common on the lower lip along the vermillion border. Given SCC on the lips is considered a high-risk form of skin cancer with an 11% chance of metastasis compared to 1% for other body locations, it is essential to recognize and appropriately manage these potentially malignant precursory lesions.
