Metastatic hepatic epithelioid hemangioendothelioma in a teenage girl

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare malignant tumor characterized by its epithelioid structure and vascular endothelium origin. The clinical course of HEHE is variable, ranging from long-term survival without treatment to a rapidly progressive course with a fatal outcome. As a consequence, no standard treatment has been determined. We present a case of HEHE occurring in a 13-year-old girl, in which a novel treatment approach using antiangiogenic therapy was tried and was successful in slowing the progression of the disease.
