Squamous Cell Carcinoma arising in Oral Lichen Planus

It has been argued that Oral Lichen Planus (OLP) may increase the risk of oral cancer. Patients with OLP may be at an increased risk for developing of OSCC (Oral Squamous Cell Carcinoma). Here, the author reports a case of OLP initially presenting with a clearly benign OLP lesion that transformed into OSCC over a course of ۱۸ months. This report may provide a clear evidence for OLP lesion as a potential pre-malignant state.
