: Squamous cell carcinoma is the most common oral cancer of the head and neck region. Up to 50 percent of these cancers have spread by the time of diagnosis; therefore, early diagnosis is vital. Oral lichen planus and epithelial dysplasia are two of the most common types of oral lesions with the potential for malignant transformation. The epidemiology and management of these conditions are discussed in this review.
