Líquen plano oral: relato de caso

Abstract

Oral lichen planus can be defined as a chronic inflammation that presents localized mucosal lesions found in various parts of the individual's body. Although the cause of the injured tissues is unknown, psychosomatic factors are usually associated with the onset of oral lichen planus. Thus, this study aims to report the following clinical case of a 50-year-old patient who sought treatment from a dermatologist to treat her lesions. The patient's chief complaint was "sores on the gums" and clinically, lesions were observed throughout the buccal gum, compatible with desquamative gingivitis, Wickham's streaks on the bilateral jugal mucosa and asymptomatic. As a complementary examination, in this case, an incisional biopsy was performed on the buccal mucosa, with histopathological findings compatible with lichen planus. Based on this result, the patient was treated with topical mouthwash with clobetasol for 30 days, and to complete the treatment systemic prednisone was prescribed for 30 days, with a significant improvement in the condition, and the patient is currently under observation. Because of the condition presented, even though there is the possibility of oral lichen planus evolving to a malignant stage, it is necessary to encourage constant monitoring of the disorder in order to evaluate the lesions periodically, so that we can slowly reduce the medications used and even change the approach if the treatment does not have the expected effect, and when necessary, involve other health specialties.
