title: Subjectivity in evaluating oral epithelial dysplasia, carcinoma in situ and initial carcinoma.
abstract: During the 2nd Meeting of the International Association of Oral Pathologists in Amsterdam (1984), an exercise was held to study subjectivity in evaluating oral epithelial dysplasia. A poster with 9 color photomicrographs was presented to be evaluated anonymously by the participants. A total of 72 submitted diagnostic suggestions. In Table 1 these suggestions are given together with the diagnosis by the authors. A surprisingly wide spectrum of diagnostic suggestions was found indicating the need for an internationally accepted set of criteria for oral epithelial dysplasia.
