Clinicopathological comparison and cytokeratin-10 expression between Lichen planus and oral lichenoid lesions.

Objectives: This study aimed to compare clinicopathological features and immunostaining for cytokeratin-10 between oral lichen planus and oral lichenoid lesions.

Design: This was a retrospective longitudinal study comparing lichen planus and oral lichenoid lesions diagnosed at the Oral Pathological Anatomy Service that analyzed sociodemographic and clinicopathological data and CK10 expression. Chi-square tests, Fisher's exact tests and Mann-Whitney tests or Student's t tests were used when appropriate, and p values < 0.
