Abstract
Hepatic epithelioid hemangioendothelioma (HEHE) is a rare malignant tumor of vascular origin. Classically, HEHE is typically associated with imaging demonstrating multifocal heterogeneously enhancing hepatic nodules and histologic examination revealing mixed epithelioid and dendritic cells in a proliferative fibrous stromal background. While generally described as a low-to-intermediate grade indolent tumor, it is essential to establish the presence or absence of extrahepatic spread when considering transplant candidacy. We describe one case study in which a transplant was denied to a unique metastatic pattern of HEHE to the superior vena cava. This is a previously unreported location of metastasis of HEHE and may serve to broaden our current understanding of potential metastatic sites for this disease.
