==Overview==
==[[Hemangioendothelioma overview|Overview]]==


'''Hemangioendothelioma''' is used to describe a group of vascular neoplasms that may be considered [[benign]] or [[malignant]] in their activity. They have been described as masses that fall between a [[hemangioma]] and [[angiosarcoma]]. They are [[vascular tumor]]s that commonly present with an enlarging mass and have been reported in the [[head]] and [[neck]], [[intestines]], [[lungs]], [[lymph nodes]], [[pleura]], [[retroperitoneum]], [[stomach]], and many other body sites. Surgical [[resection]], [[radiotherapy]], and [[chemotherapy]] have all been used to treat these masses.
==[[Hemangioendothelioma classification|Classification]]==


In hemangioendotheliomas, the cell of origin is the endothelial cell, and they range from benign to frankly malignant lesions.
==[[Hemangioendothelioma historical perspective|Historical Perspective]]==


They typically occur in young patients, especially in the soft tissues of the limbs and are often closely related to veins, from which they are thought to arise. Less frequently they can arise in bone (osseous haemangioendothelioma), in which case they are most often seen in the calvaria, spine or lower limbs.

*Epithelioid
*Kaposiform

==[[Hemangioendothelioma epidemiology and demographics|Risk Factors]]==


Radiologically they appear the same as angiosarcomas and haemangiopericytomas.
==[[Hemangioendothelioma screening|Screening]]==


===X-rays===
==[[Hemangioendothelioma causes|Causes]]==


Nonspecific soft tissue mass. When involving bone, they are predominatly lytic, and may mimic haemangiomas with a course honeycomb appearance.
==[[Hemangioendothelioma differential diagnosis|Differentiating Hemangioendothelioma from other Diseases]]==


===Angiography===
==[[Hemangioendothelioma natural history|Natural History, Complications & Prognosis]]==


Dense, well-circumscribed areas of enhancement with early draining veins and shunting. Hemangiopericytoma are described as having a pedicle formed by the arteries supplying the tumor from which vessels branch to encircle the tumor.

===CT===


Non specific soft tissue mass, with density similar to muscle but demonstrating bright contrast enhancement. CTA may demonstrate large feeding vessels.

Brightly enhancing soft tissue mass, often hyperintense on T2WI, with prominant flow voids, most marked in hemangiopericytomas.
