Background and Aim: Exact and reliable diagnosis is the result of positive correlation and concordance between clinical and pathological diagnosis. The aim of the present study was to investigate the existing concordance between clinical and pathological diagnosis. Materials and Methods: In this cross – sectional study, oral lesions files, from archive of Razi pathological laboratory in Rasht during 2000 – 2002 were reviewed and necessary information including age, sex, location of lesion, clinical and histopathological diagnosis, and surgeons specialties were recorded. Concordance between clinical and histopathological diagnoses was calculated using kappa test. Results: The total number of 466 oral lesions were recorded out of them 81 cases (17.38%) did not have any clinical diagnosis. Sensitivity range was between 40% to 79%. No concordance was found between lesion location and surgeon specialty. Reactive lesions of soft tissue were the most common ones (22.1%). The most concordance was found in mucocutaneous lesions diagnosis (k=0.77) and then in retentional salivary lesions (k=0.72). However, cystic lesions (k=0.52), reactive lesions of soft tissue (k=0.52) and infectious lesions (k=0.29) showed less agreement. Conclusion: Considering the lack of clinical diagnosis in too many cases and low level of sensitivity in this study, further evaluation for the removal of the mentioned complications is necessary. Moreover, careful review of clinical symptoms in cystic, reactive and infectious lesions is recommended. Key words: Clinical diagnosis – Histopathological diagnosis – Oral lesions – Concordance.
