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.
