Lichen Planus

Oral lichen planus is a common skin condition that affects the oral tissues. It is caused by an immune-mediated defect in the tissues, and generally affects older individuals. It can take on several clinical presentations from white lines on the buccal mucosa, to ulcerated, red lesions on the tongue and gums.
Histopathology is very helpful in the final diagnosis, and the lesions are managed with the use of topical or systemic corticosteroids or other immunomodulatory agents, depending upon the severity of the lesions.
