One-in-a-million people are living with EHE worldwide.

Our mission is to find treatments and a cure for epithelioid hemangioendothelioma (EHE) by advancing research and driving collaboration among patients, researchers, and clinicians.

We envision a world where Epithelioid Hemangioendothelioma (EHE) is easily diagnosed and treatable. Join our dedicated community by subscribing to our emails.

With the generosity, heart, and determination of the EHE community and the EHE Foundation Board of Directors, we raised more than $155,000 — and counting — for EHE Research this Giving Tuesday! In a world with so many urgent needs, we are profoundly grateful for how this community continues to show up for one another to advance our mission of finding treatments and a cure for EHE. Thank you!

Patient-Powered EHE Research

EHE Biobank

Patients are the key to finding new treatments for EHE! Researchers need tumor tissue and fluid from EHE patients to understand disease progression and speed the development of new drugs and therapies.

Patient-Powered EHE Research

EHE Global Patient Registry

The EHE Global Patient Registry empowers people with Epithelioid Hemangioendothelioma (EHE) to join together to improve our understanding of this ultra-rare sarcoma. We need every EHE patient to join this critical tool used to support researchers searching for treatments and a cure for EHE.

Scientists know that most EHE tumors are caused by specific genetic changes called gene fusions. In most people with EHE, two genes, WWTR1 and CAMTA1, are abnormally fused. In a smaller number of cases, a different fusion involving YAP1 and TFE3 is present. In a recent review published in Critical Reviews in Oncology/Hematology, the authors […]

Exploring a treatment option for hepatic EHE: Subsegmental Bland Embolization

Exploring a treatment option for hepatic EHE: subsegmental bland embolization

By EHE Foundation | December 17, 2025

A recent study published in Cancer Control describes a treatment approach for hepatic (liver) EHE called subsegmental bland embolization, which blocks blood flow to individual tumors. In three patients with multiple liver tumors, most treated tumors shrank significantly, and the disease was initially controlled in all patients. The procedure was well tolerated, with no serious […]
