Abstrakt: Aim: To investigate the correlation between the clinicopathological characteristics, serum antinuclear antibody (ANA) and direct immunofluorescence (DIF) findings in oral lichen planus (OLP) and oral lichenoid lesion (OLL).
Methods: Fifty three Thai patients with red and white lesions were divided into 3 groups: 17 cases of OLP, 19 cases of OLL and 17 cases of oral lichenoid drug reaction (OLDR), respectively. The medical records, photographs, histopathological evaluation and laboratory ANA and DIF results were analyzed.
Results: Atrophic pattern was the most commonly found pattern in the OLDR, OLP and OLL groups. In the OLP group, the DIF interpretation confirmed only 41.2% of cases as OLP, with 23.5% each as lichen planus (LP)/lupus erythematosus (LE) or negative findings. In the OLL group, the most common DIF interpretation (31.6% each) was LP/LE or non-specific finding. In the OLDR group, DIF interpretation was OLP or LP/LE (23.5% each), with 5.9% each of immune complex-mediated disease, compatible with OLP, and mixed connective tissue disease. Interestingly, 1 case in the OLDR group demonstrated mild to moderate dysplasia. There were no significant differences in ANA positivity or patterns between the 3 groups.
Conclusion: An OLP-like lesion could be diagnosed as OLP, OLP/LE, chronic ulcerative-like lesion, immune-mediated disease or dysplasia.
