Hemangioendothelioma: A Rare Entity at an Unusual Location

Abstract

Abstract Epithelioid hemangioendothelioma (EHE) is a rare type of vascular tumor that behaves in a manner halfway between benign hemangiomas and malignant angiosarcomas. It is histologically distinguished by angiocentricity and solid, cord-like arrangements of epithelioid cells with intracytoplasmic lumina containing red blood cells. Although uncommon in childhood, it can develop at any age and affects both sexes equally. Accurate diagnosis may require further evaluation with tru-cut biopsy due to its potential for false-positive metastatic cancer diagnoses. Treatment approaches vary based on symptomatology, ranging from regular follow-ups for asymptomatic patients to surgical resection with embolization for symptomatic cases. With the help of this case, we want to discuss the importance of considering EHE in the differential diagnosis of vascular lesions and the significance of tailored treatment strategies based on individual patient characteristics.
