Hepatic morphology and histochemistry of Wilson's disease presenting as fulminant hepatic failure: a study of 11 cases.
Eleven cases of Wilson's disease presenting as fulminant hepatic failure were analysed retrospectively to determine the specificity or otherwise of the histological findings. All cases were cirrhotic, eight with a micronodular pattern. There was marked parenchymal collapse with ductular proliferation and mild inflammation. Other features included cholestasis, hepatocyte necrosis, microvesicular fat and nuclear vacuolation. Orcein staining demonstrated copper-associated protein in the periphery of cirrhotic nodules in all cases and also variably within nodules in eight cases. Copper was demonstrable by the rhodanine method in similar locations but the staining reaction was qualitatively weaker in all cases. Characteristically, there was staining of both parenchymal and mononuclear phagocytic cells. This triad of cirrhosis, strong copper-associated protein deposition and copper positivity was not present in a control group of 20 cases of fulminant hepatic failure of other aetiology and with a similar clinical presentation. It is concluded that in the clinical context of fulminant hepatitis the presence of cirrhosis should raise the suspicion of Wilson's disease and that, with routinely processed and stained tissue, including autopsy tissue, the diagnosis can be made histologically.
