An extremely rare case of splenic rupture at the site of metastasis of hepatocellular carcinoma is reported. A 62-yr-old woman with hepatocellular carcinoma and its suspected metastasis to the spleen died of intraperitoneal hemorrhage. Autopsy disclosed a laceration of the spleen as the definitive cause of the hemorrhage. There were multiple nodules of metastatic hepatocellular carcinoma in the spleen, some of which were exposed at the lacerated portion of the splenic capsule. This may be the first report of a case of spontaneous rupture of the spleen secondary to metastatic hepatocellular carcinoma. Splenic rupture can be one of the causes of hemoperitoneum in patients with hepatocellular carcinoma.
