Actinic cheilitis: guidance on monitoring and management in primary care

Actinic cheilitis is an oral potentially malignant disorder caused by UV radiation leading to damage to epithelial keratinocytes of the lips. It predominantly affects the vermillion border of the lower lip. Due to its association with chronic UV exposure, associated risk factors include geographic areas, outdoor occupations, and skin subtypes. A high proportion of lip squamous cell carcinomas arise from actinic cheilitis lesions, with histological examination usually showing a degree of dysplasia. This paper aims to review the existing literature regarding the clinical picture of actinic cheilitis, its prevalence, differential diagnoses, and consensus on management, for the education of the general dental practitioner in identifying and surveillance of this lesion.
