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.

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.

Understanding Quality of Life for People Living With EHE

By Kristianne Oristian, PhD | February 10, 2026

The European Organisation of Research and Treatment of Cancer (EORTC) is conducting research to better understand health-related quality of life (HRQoL) concerns among people living with rare cancers. Recently, researchers analyzed results from a group of 31 people with EHE from 11 different countries who participated in the study. The findings showed that pain–and the […]

Exploring Eribulin as a Potential Treatment Option for EHE

By Kristianne Oristian, PhD | February 10, 2026

Prior research has shown that a class of medications called microtubule inhibitors may be effective at controlling the growth of EHE tumors. Recently, researchers conducted a phase 2 study to test whether the microtubule inhibitor eribulin is a safe and effective way to treat patients whose tumors continued to grow after prior treatment. Six (6) […]

Reflecting on 2025 and Looking Ahead With Purpose

By EHE Foundation | January 20, 2026

For the global EHE community, 2025 brought challenges, resilience, and momentum. Grounded in connection and a shared commitment to progress in EHE, we look back with emotion, appreciation, and gratitude, and in 2026, we look forward with determination and hope.

Translating molecular mechanisms of EHE to improve patient outcomes

By Kristianne Oristian, PhD | December 17, 2025

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 […]

EHE in Canada: what a national study tells us

By Kristianne Oristian, PhD | December 17, 2025

A recent study published in the European Journal of Cancer represents the largest collection of data from people with EHE in Canada. Researchers found that EHE can behave very differently from person to person—about one-third of patients were diagnosed by chance and did not need immediate treatment, while others had more aggressive disease. About half […]

Pulmonary EHE: a case report and review of literature

By Kristianne Oristian, PhD | December 17, 2025

In a recent issue of AME Case Reports, a team led by Dr. Clifford Atuiri describes a case of pulmonary epithelioid hemangioendothelioma (EHE) and places it within the broader understanding of the disease. The authors note that EHE in the lungs can be difficult to diagnose because symptoms and imaging often resemble more common lung […]
