ORAL LICHEN PLANUS – CLINICAL FEATURES,HISTOPATHOLOGY AND TREATMENT
Author: Sanketh DS, MDS
Lichens are primitive plants composed of algae and fungi. Planus means flat in Latin. Erasmus Wilson coined this term, probably because he thought the lesion was similar to the lichens growing on rocks.
Lichen planus is chronic muco-cutaneous disease of auto-immune origin, affecting around 0.2 – 2 % of the population. It could appear in the skin, in the oral mucosa or sometimes both. Oral lichen planus(OLP) could either accompany the cutaneous/skin lesions or precede them.
