Erosive oral lichen planus and its management: a case series.

Lichen planus (LP), although a dermatosis, is more common in the oral mucous membrane than in the skin. Lesions of oral LP are classically found on the buccal mucosa and gingiva. Among the various types, the reticular lesions are asymptomatic and require no treatment, but pain and severe discomfort accompany the erosive or ulcerative lesions. Malignant transformation to squamous cell carcinoma developing in areas of erosive oral LP (EOLP) being a possibility, it is important for clinicians to maintain a high index of suspicion for all intraoral lichenoid lesions. Therefore, periodic follow-up of all patients with EOLP is recommended. In view of the above, this paper highlights the management of four cases of EOLP with topical corticosteroid and CO2 laser surgery.
