title: Solar cheilitis.
abstract: Solar cheilitis is a premalignant lesion seen predominantly on the vermilion of the lower lip in light-complexioned, middle-aged men who have spent considerable time outdoors. The lesions most likely to be dysplastic or neoplastic are those with heavy keratinization, erosion, ulceration, and erythema. Lips with any of these changes should be biopsied. The most common therapeutic modality is surgical excision of the affected area of vermilion. Well-planned and well-executed procedures provide good functional and cosmetic results.
