Identifying factors associated with diagnostic concordance/discordance in oral lichen planus.

Purpose: To identify factors associated with concordance and discordance between clinical and histopathologic diagnoses of oral lichen planus lesions.

Materials And Methods: A retrospective analysis was conducted on all study cases derived from archival oral pathology reports generated from all cases of oral lichen planus accessioned by the Faculty of Dentistry, University of Malaya. These study cases were diagnosed from January 1980 through December 2010.

Neoplasia/dysplasia surveillance of oral lichen planus in Malaysia: a preliminary study using topography maps.

Background: Conventional methods for writing case notes detailing the progress of oral lichen planus (OLP), a precancerous condition that requires long-term surveillance, is both time-consuming and tedious for the busy clinician.

Objectives: To design and perform a simple surveillance on OLP patients based on colour-coded topography mouth maps (TMM).

Materials And Methods: Three colour-coded TMM were employed: red for OLP in high risk oral mucosal sites, yellow for cases showing improvement and green for asymptomatic lesions at each recall visit.
