Abstract
Objective: Is to report an Oral Bullous Lichen Planus case, exposing clinical and histopathological characteristics of the injury. Case detailing: Patient female, 86 years old, attended the service, complaining about a “protrusion” on the hard palate. On the intraoral examination, a smooth, irregular and symptomatic red plaque was detected. The hypothesis diagnosed was erythroplakia. An incisional and microscopically observed mucosal fragments were coated with stratified atypical keratinized squamous epithelium with areas of epidermis, hyperkeratosis, exocytosis and hydropic degeneration of the basal layer and the conjunctive epithelial junction presented with subepithelial bubble and focal area of projection in teeth. After being diagnosed, the patient was submeter to drug therapy and is being followed up. Final considerations: The knowledge of this pathology is of fundamental importance, for the early diagnosis and appropriate treatment, whereas it is a rare injury and difficult diagnostic.
