title: Lichen planus and hepatitis C virus in the northern Kyushu region of Japan.
abstract: Oral lichen planus (OLP) is a common oral disorder that manifests a mucosal reaction to a variety of aetiological factors, including liver disorder. This study investigated the relationship between OLP and hepatitis C virus (HCV) infection by studying the prevalence of hepatitis B and C virus infection or liver disease in 45 patients with OLP in the Northern Kyushu region of Japan where the prevalence of HCV infection is the highest in the country. Serum hepatitis B virus surface antigen (HBsAg) was positive in only four patients. Serum anti-HCV or serum HCV RNA was positive in 28 (62%) and 27 (60%) of 45 OLP patients, respectively. The majority (35 of 45, 78%) of OLP patients suffered from liver disease, including chronic hepatitis C (22/45, 49%), HCV-related liver cirrhosis (two), and HCV-related hepatocellular carcinoma (two). These results suggest that HCV is a major cause of OLP.
