title: Concurrent oral lichen planus and primary sclerosing cholangitis.
abstract: Four patients with concomitant oral lichen planus (OLP) and primary sclerosing cholangitis (PSC) are presented. Associations have been made between OLP and chronic liver disease, namely hepatitis C and primary biliary cirrhosis, but the aetiology and commonality between the diseases has yet to be confirmed. An immunological link is currently favoured. PSC may be a further association with OLP, possibly involving the immune system.
