Lichen planus.

During the past year, few articles have been published regarding the various aspects of oral lichen planus. The work reported dealt with a variety of aspects including patient profile, immunopathogenesis, and treatment. The papers served to confirm previous concepts of an immunologic etiology, the demographic consensus on patient profiles, and the use of topical or systemic corticosteroids as the most effective treatment approach. This review also summarizes some highlights of previous studies of oral lichen planus prior to 1990 and summarizes a current unpublished prospective study reflecting the findings in a large number of patients with oral lichen planus who have been followed for a long period of time.
