Abstract:
Epithelioid hemangioendothelioma is a rare vascular tumor with intermediate malignity and metastasis risk. It presents epithelioid cells with intracytoplasmic vacuoles and low mitotic activity. Its vascular nature can be confirmed by immunohistochemical studies (vimentin, CD31, CD34, and factor VIII). It is extremely rare in the nasal cavity, with only one case reported on the middle 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.
