Abstract
Epithelioid hemangioendothelioma (EHAE) is a vascular tumor which, due to its rarity, is often misdiagnosed as other hepatic tumors based on radiological characteristics. We herein report a case of EHAE in the liver and the mesentery of the small intestine. A 64-year-old asymptomatic woman was admitted to the hospital due to a hepatic tumor identified using computed tomography (CT). An enhanced CT scan revealed multiple tumors in the liver and a tumor in the mesentery. One of the hepatic tumors and the mesenteric tumor were resected and histologically examined. The two tumors exhibited similar histological characteristics and were diagnosed as EHAE. When multiple tumors are found in the liver, EHAE should be included in the differential diagnosis, as the prognosis of EHAE differs from that of carcinoma or benign tumors.
