Abstract
A case of malignant epithelioid hemangioendothelioma of the liver mimicking veno-occlusive disease is reported. The histological, ultrastructural, and immunohistochemical features of the present case indicate striking similarities to epithelioid hemangioendothelioma (EHE) of the soft parts described by Weiss and Enzinger. Tumour metastasis to the lung gave a picture closely resembling intravascular bronchiolo-alveolar tumour (IVBAT) of the lung. EHE of the liver is considered to be a unique type of hepatic endothelial neoplasm behaving as a low grade malignant tumour with a veno-occlusive process which has rarely been described, and had previously been classified as other diseases or neoplasms.
