Liver transplantation for local disease is the treatment of choice. In the metastatic setting there is no consensus regarding the appropriate systemic treatment. We present two cases of metastatic hepatic epithelioid hemangioendothelioma (hEHE) treated with the combination of Doxorubicin and Olaratumab. Both patients showed Stable Disease (SD) as a response, after the completion of six cycles of this combination therapy.Keywords: Olaratumab and Doxorubicin, metastatic hepatic epithelioid hemangioendothelioma, 1st line treatment
