Various faces of lichen planus

Background: The clinical appearances of oral lichen planus (OLP) are very characteristic. Andreasen in 1968 divided OLP in reticular, papular, plaque, atrophic, erosive, and bullous types. Gandalfo et al and Carbone et al divided OLP into white lichen and red lichen. OLP lesions are not homogenous and some cases may present as a mixture of various clinical subtypes causing difficulty in categorizing them. Aims and objective: The present study attempts to elucidate the various clinical types of OLP and categorize them appropriately. Methods: An observational study was carried out in the department of Oral Medicine and Radiology on 60 patients, diagnosed of OLP based on clinical grounds. All selected patients were categorized in 3 clinical types; reticular (including plaque and papular variety), atrophic and erosive (including ulcerative and bullous variety). In case of simultaneous presence of subtypes the severe form was considered. Results: In our study, red lichen was more common than white lichen affecting 65% of patients with near about equal distribution of reticular (35%), atrophic (40%) and erosive (25%) lichen planus. Female predominance was found in all the types of OLP. The buccal mucosa was the most common site of involvement followed by gingiva, gingivobuccal sulcus and tongue. Conclusion: Since the variants of OLP have overlapping presentation having reticular striae as a diagnostic feature in all forms, it is best to classify OLP as red and white lichen to avoid differences amongst clinicians.
