Abstract

Oral potentially malignant disorder (OPMD) is a broad term that encompasses anything that has a risk of progressing to oral cancer, including clinically normal oral mucosa. OPMDs includes both strictly clinical conditions (e.g., leukoplakia, erythroplakia, and erythroleukoplakia) and a variety of diagnoses that have well-established clinical and histologic characteristics (e.g., submucous fibrosis, dyskeratosis congentia, smokeless tobacco keratosis, chronic candidiasis lichen planus, discoid lupus erythematosus, syphilitic glossitis, and actinic keratosis). In contrast, dysplasia is a histological diagnosis that describes “abnormal growth” at the cellular level, as its name implies. The diagnostic criteria for epithelial dysplasia includes both architectural and cytological epithelial changes that serve as evidence of the cellular misbehavior that is thought to progress to oral squamous cell carcinoma (OSCC). However, although a plethora of grading scales, models, and biomarkers exist, no one has been able to reliably predict if and when epithelial dysplasia will traverse the basement membrane and invade the underlying connective tissue to progress to OSCC. This leaves clinicians with a difficult conundrum in the management and surveillance of these historically controversial conditions.
