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.
