A case of hepatic epithelioid hemangioendothelioma that caused extrahepatic metastases without intrahepatic recurrence after hepatic resection

Epithelioid hemangioendothelioma is a neoplasm of vascular origin with a low-to-intermediate malignant potential and is one of the rare sarcomas arising from the liver. Its etiology is unknown and its clinical outcome is unpredictable. There is no generally accepted therapeutic strategy because of its rarity and the variable natural course between hemangioma and angiosarcoma. We report a case of a 64-year old woman who underwent hepatic resection due to epithelioid hemangioendothelioma in the right lobe that progressed to extrahepatic metastases of the bone, pleura, and peritoneum 22 months later. However, after resection there was no primary hepatic recurrence.
