Study Notes
Surface Lesions of the Oral Mucosa
- White lesions result from light scattering due to altered mucosal surfaces.
- Mucosal changes include hyperkeratosis, hyperplasia of the stratum malpighii, and intracellular edema of epithelial cells.
Etiology of White Lesions
- Causes include physical trauma, tobacco use, genetic abnormalities, mucocutaneous diseases, and inflammatory reactions.
Categories of White Lesions
- Include hereditary conditions, reactive lesions, and other non-epithelial (e.g., yellow) lesions.
Hereditary Conditions
- Leukoedema, White Sponge Nevus, Hereditary Benign Intraepithelial Dyskeratosis (HBID), and Follicular Keratosis.
The Epidermis
- Protective outer layer of cells, approximately 0.12mm thick, regenerates every month.
Common Terminologies
- Hyperplasia: Increase in cell number leading to organ enlargement.
- Dysplasia: Abnormal development or epithelial anomalies.
- Hyperkeratosis: Thickening of the stratum corneum, often due to excess keratin.
- Parakeratosis: Keratinization with retained nuclei in the stratum corneum.
- Dyskeratosis: Premature keratinization below the stratum granulosum.
- Acanthosis: Diffuse epidermal hyperplasia indicating thickening of stratum basale and spinosum.
- Acantholysis: Loss of cell connections, leading to decreased cohesion among keratinocytes.
Leukoedema
- Primarily affects the black population.
- Causes are not definitively known but can be linked to smoking, alcohol ingestion, bacterial infections, and poor oral hygiene.
White Sponge Nevus
- Clinical features include asymptomatic, symmetrical gray-white diffuse surface lesions with textural changes.
- Histopathology shows parakeratotic and acantholytic epithelium with marked intracellular edema.
- Differential diagnosis includes leukoplakia and HBID; stretching helps differentiate lesions.
- No treatment is required, as it is non-malignant.
Hereditary Benign Intraepithelial Dyskeratosis (HBID)
- Also called Witkop's disease; follows an autosomal dominant pattern.
- Characterized by early onset symptoms, including bulbar conjunctivitis and a range of oral lesions.
- Oral lesions appear soft, white, and elastic, affecting various mucosal sites and intensifying with age.
Follicular Keratosis
- Inherited as an autosomal dominant condition (Darier's disease).
- Manifests through skin lesions, including greasy papules and thickening of palms and soles.
- Involves keratinized oral mucosal regions causing small whitish papules.
- Histologically resembles cutaneous lesions with specific clefts and acantholytic cells.
Treatment and Prognosis
- HBID typically requires no treatment.
- Follicular keratosis may be treated with vitamin A and its analogs, noting potential side effects like cheilitis and elevated liver enzymes.
- Both conditions are non-malignant but chronic and slowly progressive with varying remission rates.
