Primary hepatic angiosarcoma: A case-based discussion of unique presentations and extrahepatic manifestations

Abstract Hepatic angiosarcoma is a rare and heterogeneous neoplasm that carries with it an especially poor prognosis. Diagnosis is challenging given that patients often present with vague, nonspecific complaints, and early multiorgan dysfunction has the potential to produce a number of unique clinical syndromes. Here, we present a case of a patient with hepatic angiosarcoma who developed cryptogenic cirrhosis, Kasabach-Merritt Syndrome (consumptive thrombocytopenia), and bone marrow fibrosis as a result of her malignant lesions. While parenchymal biopsy ultimately remains the gold standard for diagnosis, careful review of enhancement patterns on imaging may suggest malignant features in need of further investigation.
