MARQUEZ FILIU, Maricel et al. Oral manifestations of the lichen planus. MEDISAN [online]. 2013, vol.17, n.11, pp. 8023-8030. ISSN 1029-3019.

A descriptive and cross-sectional study of 102 patients with oral lichen planus, assisted in the stomatological department from the Specialties Polyclinic of "Saturnino Lora Torres" Clinical Surgical Teaching Provincial Hospital in Santiago de Cuba was carried out in order to evaluate the epithelial cellular alterations, as well as to relate them with the diagnosis and the clinical forms of this disease. Biopsies were carried out to those affected to obtain the samples of damaged tissue, which were fixed and processed with the paraffin inclusion technique. This affection had higher frequency after the second decade of life and it prevailed in the white skinned patients. The most affected topographical region was the cheek mucous. The most relevant findings in the microscopic study corresponded to the band-like inflammatory infiltrate and the vacuolizing degeneration of the epithelium basal layer.
