Resumo: Objective: To reassess the cases diagnosed as oral lichen planus (OLP) and oral lichenoid lesion (OLL) and compare their sociodemographic and clinicopathological characteristics. Study design: Records and slides of 72 cases with diagnosis of OLP and OLL were evaluated and submitted to bivariate analysis. Results: OLP prevailed (52.8%). Middle-aged, non-smoking white women with white lesions at multiple oral sites without symptomatology, clinically they were the most affected for both lesions. In LPO, bilateral lesions showing intense lymphocytic infiltrate (IL) in band, well defined and in the superficial portion of the connective tissue, with hydropic degeneration of basal layer, colloid bodies, parakeratin, hyperplastic epithelial crest and absence of epithelial dysplasia predominated. In OLL, isolated lesions presenting moderate to intense focal IL, with basal degeneration colloid bodies, hyperplastic epithelial crest and epithelial dysplasia were observed. OLP was associated with lesions that manifested bilaterally (p=0.001), well-defined IL, in band and in the superficial portion of the connective tissue (p≤0.0001). OLL was associated with the presence of epithelial dysplasia and mild dysplasia (p≤0.0001). Conclusion: Histopathology of the lichenoid IL and the presence of dysplasia alone are not sufficient for the differential diagnosis LPO and LLO, the association of clinical and follow-up data is essential.
