Abstract
Epithelioid hemangioendothelioma is an unusual vascular tumor with a borderline biologic behavior that usually involves the soft tissue of the extremities of adults. Such a neoplasm studied by fine needle aspiration (FNA) cytology, histology, electron microscopy (EM) and immunohistochemistry in a 45-year-old woman is reported. The needle aspirate readily showed the characteristic epithelioid endothelial cells with eosinophilic cytoplasm, prominent cytoplasmic vacuolization and intranuclear cytoplasmic inclusions seen in the histologic preparations, indicating the possible contribution of FNA cytology to the recognition of this neoplasm. The EM and immunohistochemical studies proved the endothelial nature of the epithelioid-appearing cells comprising the tumor.
