title: [The intraepithelial carcinoma of the mouth mucosa and its anatomo-clinical variants].
abstract: Contrary to common opinion the intraepithelial cancer of the buccal mucosa presents clinical symptoms, but they are discreet and different from those observed in an invasive carcinoma. Usually, there is leucoplakia with an erythema and an irregular keratosis or a punctuated one. There is an erythematous variation (Queyrat's erythroplasia) which is without keratinasation. Only histological evidence can confirm the diagnosis cancer. It should be differentiated against Bowen's disease and the light, intermediated and severe dysplasias.
