Epithelioid hemangioendothelioma of the radial artery

Abstract

Epithelioid hemangioendothelioma (EHE) is an extremely rare vascular tumor of intermediate malignancy. Generally it develops from the peripheral veins (usually the femoral vein). We report on a case of EHE of the radial artery, developed in a 26-year-old male patient, which presented as a solitary painless mass. He had a complete resection of the tumor and of the segment of radial artery involved. The histologic examination revealed an intravascular EHE, with low mitotic index and with insufficient histologic anormalities.

Sudden cardiac death caused by a primary intimal sarcoma of the left coronary artery

“…A few cases of sarcomas in muscular arteries have been reported as angiosarcomas [3,8,10,11]. Undifferentiated intimal sarcomas in the muscular arteries that resemble those of the aorta and pulmonary artery are extremely rare.…”

Epithelioid hemangioendotheliomia as a rare cause of blue toe syndrome

“…EHE is believed to be in the middle of the spectrum of endothelial tumors, between the benign hemangioendothelioma and the malignant epithelioid angiosarcoma. [2][3][4] Lung and liver involvement were described. 1 painful mass in either superficial or deep soft tissue.…”

A case of intravascular epithelioid hemangioendothelioma occurring 14 years after coil embolization for an extracranial internal carotid artery aneurysm

“…8 In cases originating from arteries, the origin is usually the aorta. 9 There have been three case reports of EHE originating from peripheral arteries 3-5 (occipital, 3 radial, 4 and palmar 5 arteries). In the carotid arteries, three angiosarcomas and no EHE cases have been reported.…”

“…Three cases of EHE have been reported in the peripheral arteries. [3][4][5] We report a case of EHE of the extracranial internal carotid artery, which arose from an aneurysmal lesion that was treated by endovascular coil embolization 14 years earlier.…”
