Primary hepatic angiosarcoma is a rare disease with a poor life expectancy. It is believed to be highly lethal, with near 100% mortality by one year. We report a case of a 58 year male who presented with abdominal pain and was incidentally diagnosed as having multiple liver nodules on CT scan suggestive of a tubercular lesion or a lymphoma. Primary histologic examination showed features suggestive of a metastatic adenocarcinoma due to multifocal distribution, epithelioid morphology and presence of lumina. The diagnosis of primary hepatic epithelioid angiosarcoma was finally made following immunohistochemistry which showed positivity for vascular markers.
