Abstract

Background
Primary hepatic angiosarcoma is a non-epithelial malignancy derived from sinusoidal endothelial cells, accounting for approximately 1.8% of primary hepatic malignancies. Diagnosis of primary hepatic angiosarcoma is complicated by difficulties in the qualitative radiological assessment of these tumors. Prognosis is very poor due to local recurrence and distant metastasis after liver resection or liver transplantation (LT).

Case presentation
This case report describes two patients with primary hepatic angiosarcoma who were diagnosed by histopathological examination of the explanted liver after LT. One patient had undergone living donor LT, and the other had undergone deceased donor LT. Neither showed evidence of malignancy on the pre-operative imaging tests.

Conclusions
Hepatic angiosarcoma has a very high relapse rate after LT. Pre-transplant liver biopsy may be necessary to distinguish diffuse hepatic angiosarcoma from tumors of other origin in patients with cryptogenic liver failure....
