Hepatoportal Sclerosis in patient with Systemic Sclerosis and Sjögren’s Syndrome: a rare association

Abstract

We present the case of a 51 years-old woman who was referred to our Liver Unit for suspected dysmetabolic liver disease. She had a previous diagnosis of Systemic Sclerosis and Sjögren’s Syndrome and had altered hepatic enzymes with a positive anti-Nuclear Antibodies centromeric pattern, anti-Cardiolipin Antibodies and anti b2 Glycoprotein I Antibodies. Despite complete liver assessment and disease staging was negative, the clinical course was complicated by the development of anemia, due to esophageal varices bleeding associated with worsening splenomegaly. Liver biopsy was key for reaching the diagnosis as it showed portal tracts with fibrous expansion, ductular proliferation and focal lympho-granulocytic infiltrate, reduced caliber of portal vessels, hypoplastic portal tracts, focal herniation, aberrant microvasculature and positive endothelial CD34 staining. Having ruled out any other cause of portal hypertension such as cirrhosis, blood diseases, occlusion of the hepatic and portal veins, etc., we finally concluded that the portal hypertension was due to hepatoportal sclerosis associated with Systemic Sclerosis and Sjögren’s Syndrome.
