ABSTRACT
Epithelioid hemangioendothelioma (EHE) is an uncommon vascular tumor with biological behavior intermediate between hemangioma and angiosarcoma. It rarely occurs in the oral cavity. We report a case of an 81-yr-old woman with a 2-mo history of a 2 x 2 cm2 submucosal buccal mass. Fine needle aspiration (FNA) smears were paucicellular and showed mainly single atypical large epithelioid cells in a bloody background. The atypical cells had abundant dense cytoplasm, some with fine vacuoles. Occasionally, cells with large cytoplasmic lumina were seen. Cytology preparations from fresh tissue received for frozen section revealed numerous neoplastic cells with large intracytoplasmic lumina, some of which contained red blood cells. In addition, cells with distinct intranuclear inclusions were present. Histologic sections and immunohistochemical stains confirmed the diagnosis of EHE. Although the histologic features of EHE are well recognized, reports of FNA cytology findings are sparsely existent in the literature as several case reports. The characteristic cytological features of EHE are reviewed in this report. We believe that the diagnosis of this rare tumor can be suggested when an adequate FNA specimen is obtained.
