Ghapanchi J, et al. - Authors sought to measure the serum levels of galectin-3 in oral lichen planus (OLP) disease and compare the result with that observed in healthy ones. A future tool to increase the knowledge about the possible etiology of the disease is the elevation of galectin-3 in OLP. They noted the probability of this tool to be helpful to differentiate atrophic/erosive lesions from reticular ones. The serum galectin-3 levels in OLP is evaluated for the first time in this study. Findings suggested significant elevation of serum galectin-3 levels patients with atrophic/erosive lesions vs those of reticular, but it is not related to age and gender.
