Epithelioid Hemangioma of the Orbit: Case Report

Abstract

Epithelioid hemangioma (EH) and Kimura’s disease (KD) were once considered different stages of the same disease, as they share many clinical and histopathologic similarities. Nowadays, they are considered as two different entities, but some authors still confuse these terms. Our objective is to present a case of EH occurring in a very uncommon location and to emphasize the microscopic and clinical differences between EH and KD. We present a case of EH of the orbit in an 83-year-old man diagnosed after histopathologic evaluation of a mass that was surgically removed from the orbit. The tumor showed typical microscopic appearance with pathognomonic epithelioid endothelial cells. The diagnosis was also confirmed by immunohistochemical analysis. Our case clearly illustrates typical appearance of EH and the main differences between EH and KD are thoroughly discussed.
