Study Notes

Characterization of Lesions

Following biopsy, lesions may be classified as leukoplakia, potentially with dysplasia.
Dysplasia indicates abnormal cell growth, which may lead to cancer if left untreated.

Site Involvement

Commonly affected areas include:
- Floor of the mouth
- Buccal mucosa
- Soft palate
- Tongue
Lesions typically feature well-demarcated, erythematous patches or plaques with a soft, velvety texture.

Epithelial Changes

Common histological alterations observed:
- Hyperkeratosis (thickened outer layer of skin)
- Atrophy (thinning of the epithelium)
- Epithelial dysplasia in 10%-15% of cases
- Progression to carcinoma in 6% of cases

Surgical Considerations

Widespread or diffuse lesions present challenges for excision due to risks of significant morbidity.
Potential for scarring in residual tissue following excision.
Lip shave (vermilionectomy) is recommended in cases with dysplasia:
- Involves excising vermilion mucosa and advancing labial mucosa to reconstruct the vermilion area.
