Hemangioendothelioma sarcoma

The term hemangioendothelioma describes several types of vascular neosplasms and includes both non-cancerous (benign) and cancerous (malignant) growths. The term has also been applied to those that show borderline behavior, intermediate between entirely benign hemangiomas and highly malignant angiosarcomas Epithelioid hemangioendothelioma (EHE) is an ultra-rare, translocated, vascular sarcoma. EHE clinical behavior is variable, ranging from that of a low-grade malignancy to that of a high-grade sarcoma and it is marked by a high propensity for systemic involvement. No active systemic agents are curren Epithelioid Hemangioendothelioma (EHE) is a rare cancer that belongs to the group of cancers called sarcomas. EHE is a vascular sarcoma. This means it originates in the cells that line the inside of blood vessels. 'Epithelioid' refers to the elongated shape of the cells when seen under the microscope Epithelioid hemangioendothelioma, or EHE, is a rare cancer that grows from the cells that make up the blood vessels. This cancer can occur anywhere in the body with the most common sites being the liver, lungs, and bone. It usually happens in people between 30 and 50 years of age but can also occur in young children and older people Retiform hemangioendothelioma Composite hemangioendothelioma Polymorphous hemangioendothelioma.
