Diffused hepatic angiosarcoma with Kasabach-Merritt syndrome-case report and literature review

Abstract

Background: Hepatic angiosarcoma is a rare malignant tumor featured by highly aggressive behavior and poor prognosis. There are few reports about diffused hepatic angiosarcoma with Kasabach-Merritt syndrome till now. Case presentation: A male patient with the chief complain of hepatic space-occupying lesion accompanied by disturbance of consciousness and jaundice. Hyperbilirubinemia, anemia, thrombocytopenia, prolonged prothrombin time, hypofibrinogenemia, decreased prothrombin activity, and increased fibrinogen degradation product and Ddimer were confirmed by blood analysis; multiple focal hypodense lesions in liver was detected by abdominal computed tomography. Liver failure and Kasabach-Merritt syndrome induced by hepatic hemangioma was diagnosed before operation and liver transplantation was performed. Hepatic angiosarcoma was finally proven by postoperative pathology. This patient died of tumor metastasis 2 months after operation. Conclusions: Hepatic angiosarcoma which can generate Kasabach-Merritt syndrome and even liver failure has an extremely poor prognosis; liver transplantation option should not be considered in hepatic angiosarcoma regardless of the reason.

“…A second interest seems to be the breaking mechanism. Trauma is a cause of rupture of the angiosarcomaas for angioma [4], but it canals occur spontaneously [5]. In our observation, the peculiarity is that the rupture was made either in two stages (minimal cracking followed by a frank rupture) or that there was a first rupture of the small angioma followed secondarily by that of the giant angioma.…”

Case report and review: Angiosarcoma with thrombocytopenia after total hip arthroplasty

“…According to the International Society for the Study of Vascular Anomalies classification, thrombocytopenia is not typical of AS ( 43 ). Few case reports have presented KMP associated with hepatic AS among adults ( 44 , 45 ). In KMP, PLTs are activated and trapped in the tumor.…”

Diffused primary hepatic angiosarcoma: a case description

“…To date, an expert consensus of standard adjuvant chemotherapy regimens of PHA has not been reached. Liver transplantation should not be considered in PHA as it does not increase survival outcomes, regardless of the indication ( 7 ). Research found that the probability of accepting surgery in patients with hepatic angiosarcoma was less than 20%, so early diagnosis, timely operation, and personalized adjuvant therapy are critical to improving the survival time and quality of life of patients ( 2 ).…”
