Study Notes
Oral Epithelial Dysplasia and Potentially Malignant Disorders Overview
- Oral epithelial dysplasia is characterized by abnormal mitosis, unequal division, architectural changes, cytological changes, irregular epithelial stratification, abnormal variation in nuclear size, loss of polarity of basal cells, abnormal variation in cell size and shape, and other cellular abnormalities.
- Epithelial dysplasia is graded as mild, moderate, or severe based on the degree of epithelial involvement, with severe dysplasia indicating carcinoma in situ.
- Extrinsic factors contributing to potentially malignant disorders include tobacco, alcohol, actinic radiation, chronic infections, and nutritional deficiencies, while intrinsic factors are also involved.
- Leukoplakia is a clinical term for white patches on oral mucosa that are not rub-offable and cannot be clinically characterized as any other disease, and its clinical features vary based on the site and appearance of the lesions.
- Proliferative verrucous leukoplakia and speckled leukoplakia are high-risk variants of leukoplakia, with the former being multifocal, aggressive, and having a high recurrence rate.
- Erythroplakia is a flat red patch with a soft, velvety texture that cannot be attributed to any other condition and has a 40% risk of malignant transformation.
- Actinic cheilitis is characterized by accelerated tissue damage of the lips, mainly the lower lip, due to chronic exposure to sunlight.
