A modified classification and staging system for oral leukoplakia

A proposal for a modified classification and staging system for oral leukop lakia (OLEP) has been presented in which the size of the leukoplakia and th e presence or absence of epithelial dysplasia are taken into account. Altog ether four stages are recognised. The presently proposed system should faci litate uniform reporting of treatment or management results of OLEPs in whi ch a biopsy has become available. The system can easily be adjusted by repl acing the histopathological criteria of epithelial dysplasia by a clinical subdivision in homogeneous and non-homogeneous leukoplakia for cases in whi ch no biopsy is available.
