Kaposiform hemangioendothelioma arising in the ethmoid sinus of an 8‐year‐old girl with severe epistaxis

Abstract

We report a previously undescribed cause of epistaxis in children, namely, a kaposiform hemangioendothelioma. To our knowledge, this is the first such case in the English-language literature. The differential diagnosis of severe unilateral nasal bleeding among the pediatric population should include the possibility of a kaposiform hemangioendothelioma.
