What is epithelioid hemangioendothelioma?

Epithelioid hemangioendothelioma (EHE) is a rare cancer that forms from the cells lining your blood vessels (endothelial cells). Blood vessels, including veins, arteries and capillaries, are located throughout your body. Similarly, EHE can form anywhere in your body. Most often, EHE starts in your liver, lungs or bones. However, EHE can develop in other places, including your head, neck, thyroid, stomach, ovary, prostate, brain, spine, etc.

EHE may present as a single tumor, multiple tumors in a single organ or multiple organs. Often, by the time EHE is diagnosed, tumors have spread to more than one organ.
