Oral lichen planus. Case report and literature review

Abstract

Oral lichen planus (LPO) is a chronic mucocutaneous disease, of an inflammatory nature, unknown etiology
and autoimmune nature, in which aggression by T lymphocytes directed against the basal cells of the oral
mucosa epithelium occurs. The diagnosis of LPO should be based on clinical observation and confirmed
with the description of histopathological characteristics. There is a clinical case of a 39-year-old female
patient who attended a dental office at the Stomatology Service of the School of Dentistry, Faculty of Health
Sciences, Catholic University of Córdoba for presenting multiple white lesions in the oral cavity of 1 year
of evolution. The patient manifests episodes of stress. An incisional type biopsy was performed and sent to
a pathological anatomy where the diagnosis of Oral Lichen Planus was confirmed.
