[Morphology of precancerous and cancerous cells of the oral mucosa. Changes in the epithelial surfaces (scanning electron microscopy)].

Cytological investigations of oral mucosa are very reliable. But in some cases, the distinction between dysplastic and cancerous cells is difficult. The scanning electron microscopy is able to bring morphological arguments in this eventuality. It is also useful for a best diagnosis of viral condylomas and of pemphigus vulgaris.
