Oral lichen planus as interdisciplinary problem

Relevance. Lichen planus is a subacute or chronic disease, affecting skin and oral mucous membranes. There is no accurate data oа the incidence of lichen planus is not, due to access of patients not only to dentists, but also to the dermatologists. There are typical reticular clinical form of oral lichen planus, and 6 atypical clinical: hypertrophic, exudative-hyperemic, bullous, erosive, atrophic and atypical. However, only reticular form is asymptomatic, while others are accompanied with dryness, pain and burning, and erosive form of lichen planus has statistically significant malignant potential. Purpose. The purpose of this study was to investigate the frequency of oral lichen planus in the general structure of lichen planus of the skin. Material and methods. The present study was based on screening of 338 patients with lichen planus - residents of the Moscow region. In thise group of patients were studied clinical features of different forms of lichen planus of skin and mucous membranes, especially their course and frequency of associations of skin lichen planus with oral lesions. Results. According to the study, in patients with typical lichen planus skin lesion reticular form of oral lichen planus was presented in 102 (of 30.18 %) cases and atypical forms were diagnosed in 26 (7,69%) cases. Atypical lichen planus of the skin, diagnosed in 81 patients, in 41 (50,6 %) cases was associated with oral lesions: in 12 (29,3 %) cases with reticular form, and in 29 (70,7%) with atypical forms. In 16 cases the process was isolated, localized in oral cavity and in each case it was with atypical forms. Conclusion. Oral lichen planus was diagnosed in 169 (50 %) patients with lichen planus of the skin, and with about the same (of 37.8 35.8 %) frequency it was associated with typical and atypical forms of skin lesions. The most severe and resistant to therapy was erosive oral lichen planus of the mouth, especially in vulvovaginal-gingival syndrome.
