Abstract:

Lichen planus, also known as Lichen RuberPlanus, is a common dermatosis that occurs on the skin and oral mucous membranes. Oral lichen planus(OLP) is a chronic inflammatory disease with a strong indication that its physiopathologic mechanism is autoimmune. The disease can affect any part of the oral cavity; however the lesions are frequently detected in the buccal mucosa. The mouth is involved in only one third of the cases, while another one third lesions are both oral and cutaneous. Lichen planus is considered to be a precancerous condition. In most cases, malignant transformation to carcinoma in situ (28.5%) and microinvasive carcinoma (30-38%) is observed, less frequently stage I and II carcinoma. Here we describe two different clinical types of OLP which has been diagnosed, treated and is under follow up.
