Reticular lichen planus Reticular lichen planus is characterized by a painless, white lacelike hyperkeratosis. Most common sites include the intraoral mucosa of the cheek, gingivae, tongue and lips. Lesions are found bilaterally No treatment is indicated except for periodic monitoring. Erosive lichen planus Erosive lichen planus consists of recurrent, painful, eroded mucosal areas of varying diameters. Typically found in the same areas as reticular lichen planus, the borders of these lesions exhibit a zone of radiating white striae.
Treatment consists of topical steroid therapy for moderate to severe cases.
A systemic antifungal agent should be used in conjunction with steroids to avoid a secondary fungal infection. Mucous membrane pemphigoid More common in older adult women. Produces ulcerations of the palatial mucosa and gingiva. Indistinguishable clinically from erosive lichen planus. A serious sequela of the condition is the ulceration of the conjunctiva and management must include assessment by an ophthalmologist.
