Epithelioid Hemangioendothelioma Arising from Interanl Jugular Vein Mimicking Cervical Metastatic Lymphadenopathy

Abstract

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surgery, we determined that the nodule was an intravascular tumor arising from the left internal jugular vein. The histopathological examination revealed cords of epithelioid endothelial cells distributed in a hyaline stroma, compatible with a diagnosis of EHE.
