title: A modified classification and staging system for oral leukoplakia.
abstract: A proposal for a modified classification and staging system for oral leukoplakia (OLEP) has been presented in which the size of the leukoplakia and the presence or absence of epithelial dysplasia are taken into account. Altogether four stages are recognised. The presently proposed system should facilitate uniform reporting of treatment or management results of OLEPs in which a biopsy has become available. The system can easily be adjusted by replacing the histopathological criteria of epithelial dysplasia by a clinical subdivision in homogeneous and non-homogeneous leukoplakia for cases in which no biopsy is available.
