Aim: To establish a correlation between the clinical and histopathological features in the diagnosis of Oral Lichen Planus (OLP) and Oral Lichenoid Lesions (OLL). Objective: To compare the clinicopathological features in the diagnosis of OLP and OLL based on modified WHO diagnostic criteria proposed by Van der Meij and Van der Waal in 2003 and the criteria proposed by Cheng at al (2016) for OLP. Materials and Methods: Thirty patients with a clinical provisional diagnosis of oral lichen planus, referred for incisional biopsy were clinically and histologically evaluated using haematoxylin and eosin stained sections based on the modified WHO criteria. This was compared with Cheng?s proposed criteria for OLP. Results: The number of patients diagnosed with Oral Lichenoid lesions was higher using the criteria proposed by Cheng et al.
