Oral lichen planus presents in various clinical forms: reticular, erythematous (atrophic), and erosive-ulcerative bullous. The most common is the reticular form, appearing as white lace-like plaques. These are most frequently seen on the buccal mucosa, dorsal tongue, and gingiva. The labial mucosa is also a common site. Erosive, bullous, and atrophic forms are more frequently associated with burning sensation and may cause severe pain. Bleeding may occur in the lesions. Taste disturbances and difficulty eating can also develop. It is a form that requires attention regarding the potential for cancer development.
