Incomplete septal cirrhosis associated with Wegener's granulomatosis.
Incomplete septal cirrhosis, which is included in the spectrum of hepatoportal sclerosis, is characterized by parenchymal nodularity, incomplete fibrous septa, clustered or dispersed portal tract remnants, and abnormal spacing of portal tracts and hepatic veins. Hepatoportal sclerosis is known to be associated with collagen vascular diseases. Here, we describe a 73 year-old-female with incomplete septal cirrhosis. At 57 years, she presented with respiratory symptoms, and lung biopsy disclosed active arteritis with granuloma. Perinuclear antineutrophilic cytoplasmic antibody was also positive. Immunosuppressive therapy was done under the diagnosis of Wegener's granulomatosis. At 63 years, liver dysfunction was noted, and laparoscopy revealed uneven surface of the liver and dilatation of the umbilical vein. Liver dysfunction progressed, and she developed encephalopathy and massive ascites. She died of sepsis at 73 years. At autopsy the liver (700 g) was macronodular with several deep depressions. The parenchyma showed fine and diffuse nodularity. Grossly visible portal and hepatic veins were patent. The above-mentioned histologic features characterizing incomplete septal cirrhosis were found. This is the first report of incomplete septal cirrhosis associated with Wegener's granulomatosis implying that vascular and extravascular lesions of Wegener's granulomatosis might have been related to the pathogenesis of incomplete septal cirrhosis.
