A case of hepatic angiosarcoma surviving for more than 16 months after hepatic resection.

Hepatic angiosarcoma is a non-epithelial malignant tumor and a rare primary neoplasm accounting for only a 0.1% of primary liver malignant tumors. Hepatic angiosarcoma progresses rapidly; therefore, most cases are discovered at an advanced stage, and less than 20% of the patients have received surgery. The lack of specific symptoms and radiological findings leads to the delay of diagnosis resulting in the poor prognosis. To the best of our knowledge, only three patients have been reported to survive for more than one year after hepatic resection for angiosarcoma. We herein report a patient with hepatic angiosarcoma, 4 cm in size, who underwent hepatic resection after confirming the diagnosis as angiosarcoma by the intraoperative frozen section examination. The patient is still alive for more than 16 months postoperatively without any signs of recurrence.
