The scientific evidence in dictating that oral Lichen planus is a "premalignant Lesion" is:
a. Very strong
b. Non-existent
c. Moderately strong
d. Weak. ***
- The premalignant potential of oral lichen planus and the malignant transformation rate is cited as 0.4-3.3 per cent. Whether or not patients with atrophic or erosive forms of oral lichen planus are more susceptible to malignant change has yet to be proved by long-term prospective studies.
Good prognosis; rare malignant transformation (0.5–3%).
