A case of hepatic angiosarcoma diagnosed by laparoscopic liver tumor resection

Abstract

A 73-year-old man presented with multiple space occupying lesions in both liver lobes upon chest computed tomography, which was originally conducted as a follow-up examination for the presence of pulmonary nodules. Percutaneous liver tumor biopsy revealed the absence of any malignancies. Following laparoscopic liver tumor resection, the patient was diagnosed with primary hepatic angiosarcoma. After one course of paclitaxel treatment, the patient was treated with pazopanib. However, treatment was discontinued early due to poor performance status, and the patient died approximately 4 months after initiating chemotherapy. Hepatic angiosarcoma is a rare disease with high risk of malignancies. Because accurate diagnosis via imaging is not easy, laparoscopic resection is useful for diagnosing hepatic angiosarcoma.
