We report a case of a malignant primary solitary fibrous tumor (SFT) of the liver. A 38-year-old woman admitted for abdominal pain was found in abdominal computed tomography (CT) to have a mass with enhancement below the liver and ascites necessitating emergency laparotomy due to intraperitoneal bleeding from the mass. Bleeding was stopped, and the mass was found to be a hepatic tumor of segment 6. But the tumor was not ruptured, and we guess the origin of intraperitoneal bleeding was ovarian hemorrhage. Partial hepatectomy yielded a histopathological diagnosis of SFT. The postoperative course was uneventful, but the woman died 11 months after surgery due to multiple liver and bone metastasis. Primary SFT of the liver is very rare, with only 27 cases, including our own, reported worldwide. Malignant cases are even rarer than primary hepatic SFT.
