When lip cancer arises in the context of a superficial field change lesion — leukoplakia or actinic keratosis — affecting the external vermilion, the clinical scenario calls for a specific surgical approach that addresses the affected mucosal field rather than focal lesion alone.
The patient presents with a superficial field change lesion of the external vermilion of the lip, manifesting as leukoplakia or actinic keratosis. These lesions involve a broad segment of the vermilion surface rather than a single discrete nodule, requiring management that accounts for the extent of field involvement.
A surgical technique targeting the affected vermilion field is the recommended approach. The full procedural protocol — including technique details, extent of resection, and reconstruction — is outlined in the complete evidence-based regimen.

Superficial field change lesions affecting the external vermilion of the lip such as leukoplakia or actinic keratosis are best managed via a lip shave and mucosal advancement.
