Epithelial Dysplasia at Excision Margins of Oral Squamous Cell Carcinoma: A Review on Relationship to Clinicopathological Parameters and Prognosis.

Dysplastic epithelium at excision margins may not be similar to dysplasia in Oral potentially malignant disorders (OPMD) as malignant transformation has already taken place. Therefore, management of ED at excision margins should be different to that of OPMD.
