Disappearance of Oral Lichen Planus After Liver Transplantation for Primary Biliary Cirrhosis and Immunosuppressive Therapy in a 63-year-Old Japanese Woman

Introduction: There are few reports concerning association between primary biliary cirrhosis (PBC) and lichen planus. In addition, there is only one report about lichen planus after liver transplantation.Case Presentation: We describe a case of oral lichen planus (OLP) accompanied with PBC that resolved following liver transplantation 14 years later. This patient received immunosuppressive drugs after liver transplantation. Discussion: The disappearance of OLP might be due to immunosuppressive therapy following liver transplantation. Further observations and studies are necessary to clarify the relationship between OLP and PBC.
