후비공에 발생한 상피모양 혈관내피종 1예 = A Case of Epithelioid Hemangioendothelioma on the Choana

다국어 초록 (Multilingual Abstract)

Epithelioid hemangioendothelioma is a rare vascular tumor with intermediate malignity and metastasis risk. It presents epithelioidcells with intracytoplasmic vacuoles and low mitotic activity. Its vascular nature can be confirmed by immunohistochemicalstudies (vimentin, CD31, CD34, and factor VIII). It is extremely rare in the nasal cavity, with only one case reported on themiddle turbinate in Korea. The authors present a case of epithelioid hemangioendothelioma on the choana with a size of 2mm,which easily coult have been misdiagnosed as a blood clot.
