Abstract
Immunoglobulin G4-related disease is a recently recognized entity characterized by a mass-forming or regional lesion that contains an extensive infiltration of IgG4-producing plasma cells with dense fibrosis. Immunoglobulin G4-related disease can affect any organ system, but solitary hepatic lesion of Immunoglobulin G4-related disease is very rare. This entity mimics primary malignant hepatic tumor, such as hepatocellular carcinoma or intrahepatic cholangiocarcinoma. We experienced a case of hepatic IgG4-related inflammatory pseudotumor in a 50-year-old woman, mimicking hepatocellular carcinoma.
