ESTRADA PEREIRA, Gladys Aída et al. Clinical and histopathological diagnosis of the oral erythroplasia. MEDISAN [online]. 2010, vol.14, n.4. ISSN 1029-3019.
A descriptive and cross-sectional study of 15 patients with oral erythroplasia, treated at the stomatological service of the Specialities Polyclinic belonging to "Saturnino Lora" Teaching Provincial Hospital from Santiago de Cuba was carried out, from June, 2003 to the same month of 2007, to evaluate the results of the clinical and histopathological diagnosis of this disease and to link them with the smoking habit and the subjective symptoms. Samples of the damaged areas were taken for biopsies, they were deposited in a glass flask with 10% formalin, they were fixed in 5% formalin, and processed with the classical technique of inclusion in paraffin and then they were stained with hematoxylin and eosin, which confirmed the existence of cellular changes. This disorder prevailed in the male sex and the absence of subjective symptoms was the most important observation in the smokers with longer period of this habit. The most sensitive anatomical site corresponded to the hard palate, with prevalence of the epithelial dysplasia which was moderate in the nicotine addiction cases with longer periods of it.
