In addition to ten children with Wilson's disease and one with Indian
childhood cirrhosis, nine Indian children, aged from 4 to 15 years, wi
th cryptogenic cirrhosis had significant deposits of stainable copper
in their hepatocytes. These nine children had normal or elevated serum
caeruloplasmin levels, absence of Kayser-Fleischer rings and a histor
y of sibling death owing to liver disease in four cases. Histologicall
y, fatty change was absent from all the biopsies but Mallory's hyaline
, pericellular fibrosis and ballooning of hepatocytes were present in
some. Since these children did not conform to the accepted clinical or
histological definitions of either Indian childhood cirrhosis or Wils
on's disease, they were designated as having atypical copper cirrhosis
. The relationship of this group of cases to other types of copper cir
rhosis is unknown.
