Popis: A 71-year-old man had noticed a dry sensation in the mouth with swelling of bilateral parotid glands in 1988. He was given a diagnosis of Sjögren's syndrome (SS) on the basis of characteristic findings of sialography and a minor salivary gland biopsy. He was admitted to our department in Febuary 1995 because of general fatigue of 2 month's duration. Laboratory data showed both positive anti-SSA and anti-SSB antibodies, liver dysfunction, hypoalbuminemia, and thrombocytopenia. Abdominal CT and MRI demonstrated a 2-cm intrahepatic mass (S 6) with enhanced areas at the periphery. The liver biopsy yielded fragments from the intrahepatic mass and hepatic parenchyma. The former was composed of plasma cells, lymphocytes, and histiocytes, compatible with the diagnosis of inflammatory pseudotumor of the liver. The pathological diagnosis of the latter specimen was primary biliary cirrhosis, although antimitochondrial antibody was negative. The intrahepatic mass gradually decreased in size without treatment. Inflammatory pseudotumor is considered to be a benign inflammatory condition simulating a neoplasma and the possibility of an autoimmune reaction is suggested on the basis of etiology. This is the first report of an inflammatory pseudotumor associated with Sjögren's syndrome developing in the liver. The inflammatory pseudotumor should be considered as a possible diagnosis in cases where the tumor is embedded in the liver.
