ABSTRACT
A 76-year-old woman was referred to our hospital due to massive gingival bleeding following teeth extraction. Laboratory findings suggested
disseminated intravascular coagulopathy (DIC). Enhanced computed tomography and magnetic resonance imaging disclosed
multiple hypervascular liver masses of 2-6 cm in diameter, the largest of which displaying an irregular enhancement pattern. We considered
that her DIC was caused by the multiple liver masses and commenced repeated erythrocyte/fresh frozen plasma infusion
and gabexate mesilate administration. However, the DIC proved uncontrollable and trans-arterial embolization could not be attempted.
The patient eventually died 4 months after admission due to spontaneous hepatic tumor rupture and hepatic failure. Post-mortem hepatic
tumor biopsy led to a final diagnosis of hepatic angiosarcoma with Kasabach-Merritt phenomenon (KMP). Among the 7 cases
of hepatic angiosarcoma representing KMP found in the literature, mortality occurred within 4 months of the appearance of bleeding
tendency primarily due to abdominal bleeding and hepatic failure. The possibility of hepatic angiosarcoma should be considered in patients
with DIC and hypervascular liver tumors. Since treatment is uncertain and prognosis is poor, novel diagnostic and therapeutic
advances are needed for angiosarcoma.
