Epithelioid hemangioendothelioma (HEE) is an unusual malignant neoplasm of vasculo-endothelial origin, arising in soft tissues, lung and liver. One case of hepatic HEE is reported in a 32 year-old man wit an isolated multinodular hepatomegaly. The diagnosis was made by the histologic examination of biopsy specimens. At the time of diagnosis, there was evidence of pulmonary metastasis. However, an orthotopic liver transplantation was performed. The tumor cells were immunoreactive with factor VIII-related antigen, BNH9 and vimentin. There was no expression of cytokeratin and epithelial membrane antigen. The patient is alive and well 24 months after. The thoracic X-ray are unchanged. This case is compared with the 84 others cases of the literature. Fourteen experienced a favorable outcome after transplantation. Extra-hepatic dissemination doesn't contra-indicate the graft. But hilar vascular involvement may be correlated with worse prognosis.

Epithelioid hemangioendothelioma and angiosarcoma of the liver are rare neoplasms of vascular origin. They can present with nonspecific symptoms such as malaise and weight loss, as well as with liver-related symptoms such as abdominal pain, tender hepatomegaly and jaundice. Portal hypertension and rarely liver failure can occur. We hereby report two cases of fulminant hepatic failure that were eventually diagnosed with epithelioid hemangioendothelioma and angiosarcoma of the liver.

Epithelioid hemangioendothelioma is a rare vascular origin tumor which usually occurs in soft tissues, liver, and lung. It usually affects adult women and presents as multiple hepatic nodules with mainly peripheral distribution. It is difficult to diagnose and treat because of non-specific clinical manifestations and findings on the imaging study. Moreover, pathological misdiagnosis is common. We report a case of this rare tumor that was detected incidentally. Final diagnosis was based on histological evidence. A 52-years old man suffered from right upper quadrant abdominal pain for 3 months, and was initially misdiagnosed as a metastatic carcinoma. Physical examination revealed superior cervical lymphadenopathy with mild hepatomegaly. Finally, hepatic epithelioid hemangioendothelioma was diagnosed on the basis of positive immunohistochemical staining for factor VIII, CD34, and VEGF. Our case highlights the importance of a histological diagnosis to avoid misdiagnosis.
