Malignant transformation of a potentially low risk lichenoid reaction.
J Coll Physicians Surg Pak Jan ;22(3):184-5.

Lichenoid reaction represents a family of oral lesions identical, both clinically and histologically to oral lichen planus. The triggering factor for this lesion varies from medicines to dental materials, usually demonstrating a cause-effect relationship unlike lichen planus. We present a typical case of lichenoid reaction on the buccal mucosa that appeared in response to betel quid which progressed to carcinoma during a follow-up period of 6 months. Lichenoid reactions occurring in response to known carcinogens and that occuring in risk group population has to be observed more cautiously.
