Coexistent hepatic and pulmonary epitheloid hemangioendothelioma.

ABSTRACT

Epitheloid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin known to arise in soft tissue, liver and lung. We describe a case of coexistent hepatic and pulmonary epitheloid hemangioendothelioma, proven on autopsy, and review the histological and radiological features of epitheloid hemangioendothelioma. The coexistence of hepatic with pulmonary EHE has been reported in only a few cases. Large confluent masses, peripheral location with capsular retraction, hypertrophy of uninvolved liver, invasion of portal and hepatic veins, enhancing margins and delayed enhancement and dense calcification are the typical features which provide a clue to diagnosis of hepatic EHE. In patients with both hepatic and pulmonary EHE it is difficult to say whether the tumor arose primarily in the lung or liver, or began simultaneously in both organs.
