"nBackground: Hepatitis C is a major cause of chronic liver disease and hepatocellular carcinoma. Hepatitis C infection also has extrahepatic manifestations, including cryoglobulinemia and lichen planus. Lichen planus is a relatively common mucocutaneous disorder, and, due to its chronic pattern and increased incidence of malignancy, diagnosis and treatment of this disease are very important. The aim of the present study was to investigate the prevalence of oral lichen planus in HCV-infected patients. "nMethods: In this cross sectional- descriptive study, the prevalence of oral lichen planus was evaluated by means of observation, clinical examination, questionnaire and evaluation of the medical records of 150 patients referred to the hepatitis clinic, gastrointentrology and infectious disease wards of Imam Khomeini Hospital and the Iran Blood Transfusion Organization, Tehran, Iran. We used a sequential method for sampling. Data were analyzed using statistical software (SPSS ver. 11) and the chi-square test. "nResults: From a total 150 patients, 133 were male and 17 female. Six cases (4%) had oral lichen planus. All patients with oral lichen planus were male and the buccal mucosa was the most common site. "nConclusions: According to this study, the prevalence of oral lichen planus in patients afflicted with HCV is higher than in the normal population. We should pay more attention to oral lichen planus as one of the extrahepatic manifestations of hepatitis C.
