Traumatic ruptured hepatocellular carcinoma (HCC) is very rare, and only 16 cases have been reported, to our knowledge, in the English and Japanese literature. We report a new case, summarizing the 16 reported cases. A 69-year-old man was admitted to an emergency hospital due to shock after a traffic accident. Computed tomography (CT) demanstrated the rupture of HCC at segment 8 of the liver and transcatheter arterial embolization (TAE) was subsequently carried out. He recovered from the initial critical condition, and was transferred to our department for further treatment. Although HCC, 6 cm in diameter, was detected in segment 8 of the liver, no viable HCC could be observed in CT, so he was discharged and carefully followed up. Seven months later, a few viable nodules were detected around the HCC treated by TAE. Segment 8 of the liver was anatomically excised together with the adhering omentum and diaphragm. Washing cytology in the abdominal cavity showed findings for cancer to be negative. Histologically, viable well-differenciated HCC was evident around the necrotic tumor. He was discharged on postoperative day 14 and remains alive 8 months after surgery with bone metastasis.
