Scanning electron microscopic study of oral leukoplakia*

Abstract
Biopsy specimens of buccal mucosa from 6 oral leukoplakia patients and 1 specimen of normal buccal mucosa were studied by scanning electron microscopy. The results showed: difference between the surfaces of normal and leukoplakic epithelial cells; variation with the clinical type of leukoplakia: in leukoplakia verrucosa, epithelial cells appeared keratinized; in leukoplakia erosiva, epithelial cells were dissociated; histologically, dysplastic erosive leukoplakia was characterized by an atypical arrangement of superficial cytoplasmic projections of epithelial cells.
