An acute progressing hepatic angiosarcoma in a young male diagnosed by contrast-enhanced ultrasound-guided liver needle biopsy: a case report

Primary hepatic angiosarcoma (PHA) is a rare hepatic malignancy primarily observed in the elderly. It carries a poor prognosis as a result of the characteristics of rapid progression, high aggressiveness, and resistance to traditional chemo- and radiotherapies. Its nonspecific clinical manifestations, along with the lack of laboratory features and various imaging findings, make it hard to recognize in clinic, especially among non-high-risk populations. Hence, pathological diagnosis is essential to establish an accurate diagnosis.
