After the identification of the hepatitis C virus genome in 1989 and after the first medical publication on the association between hepatitis C virus and lichen planus (in 1991), medical literature has become controversial on this subject. The present material reviews the literature and the major world point of views reported in the last 20 years. Recent epidemiological studies indicate that hepatitis C virus is more prevalent in patients with lichen planus than in control populations. Screening for antihepatitis C virus antibodies is a currently recommended approach in patients with lichen planus.
