LICHEN PLANUS. Most of us are sure to across this interesting term when we look through information regarding auto-immune disorders. The term is itself inspired by the lichen plant that usually covers rocks and trees in a mossy, web-like fashion, similar to the disorder’s clinical appearance.
It is a chronic immune disorder that can affect the skin, oral mucosa, scalp, genital mucosa, and nails. Oral lesions have often been seen in the absence of skin lesions. It is in fact, one of the most common dermatological diseases to affect the oral cavity with a prevalence rate of about 0.5% to 2%.
The fact that distinguishes the Oral Lichen Planus (OLP) from other variants is that lesions inside the oral cavity rarely undergo spontaneous remission, whereas cutaneous lichen planus lesions are more or less self-limiting. Hence, early and accurate diagnosis becomes all the more essential to give symptomatic relief to the patients from the bothersome pain and sensitivity of the ulcerative or erosive lesions while it takes months to years for getting completely resolved.
