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.
