Infantile hemangioendothelioma of liver: report of two cases.

Infantile hemangioendothelioma, the commonest mesenchymal tumour of liver in infancy, though benign in nature, may behave aggressively. Here reports of two such cases are presented. Both were girls and less than 1-year old. Grossly, they presented with nodular hepatic masses with features of heart failure. Histopathology of both liver masses showed intercommunicating bloodvessels, lined by single layer of plump endothelial cells showing CD-34 positivity by immunohistochemistry. Entrapped biliary channels within tumour mass showed cytokeratin positivity.
