Ultrastructural pathology with normal light microscopy of liver in Wilson's disease. A case report.
Light microscopy findings in early Wilson's disease (hepatolenticular degeneration) may be normal even when special cytochemical stains are used. We present a case of Wilson's disease in which light microscopy was negative, while electron microscopy showed the characteristic changes in the hepatocytes. Since low serum ceruloplasmin levels and high urinary copper excretion are not by themselves definite proof of Wilson's disease, and since copper content of the liver is not universally measured, electron microscopy examination of liver tissue appears to be a worthwhile additional tool for the early diagnosis of Wilson's disease.
