Key result
Surgical resection of a small primary hepatic angiosarcoma yields ~8 months of recurrence-free survival.
Why the study?
Primary hepatic angiosarcoma is difficult to diagnose preoperatively due to lack of specific symptoms or tumor markers, and few reports describe tumors smaller than 2 cm.
Case Report (n=1)
No
Reports a rare case of a small (1.7 cm) primary hepatic angiosarcoma diagnosed and treated with surgical resection.
May support resection of small hepatic angiosarcomas; leaves open whether size improves outcomes in this rare malignancy.
Primary hepatic angiosarcoma is a rare tumor originating from endothelial cells in the liver and accounts for approximately 1% of all hepatic malignant tumors. It is difficult to diagnose due to the lack of specific symptoms or tumor markers. No effective treatment exists, but complete surgical resection may achieve a good outcome. Since most primary hepatic angiosarcomas are already at an advanced stage at diagnosis, few reports describe tumors smaller than 2 cm. We report a case of surgery for a 1.7-cm sized primary hepatic angiosarcoma. Further studies are required to improve the preoperative diagnosis of primary hepatic angiosarcoma.

Tsunematsu et al. (2017) conducted a case report in Primary hepatic angiosarcoma (n=1). Surgical resection was evaluated on Survival without recurrence. Surgical resection of a 1.7-cm primary hepatic angiosarcoma, one of the smallest described in the literature, resulted in survival for more than eight months without recurrence.
