Comparative study of number and distribution of IgG[+] cells in oral lichen planus and oral lichenoid lesions

ABSTRACT

Background: oral lichen planus is a common mucocutaneous disorder with unknown etiology. While current data suggest that oral lichen planus is a cell-mediated disease, differential diagnosis of this disease and oral lichenoid lesions is very problematic, both clinically and histopathologically. This study aimed to compare immunohistochemical features of these similar diseases
