Rupture of hepatocellular carcinoma (HCC) is a lifethreatening complication.Peritoneal metastasis of HCC after spontaneous rupture was seldom noted.We report a case of intraperitoneal metastasis of HCC after spontaneous rupture.A previously asymptomatic 72-year-old man was admitted due to dull abdominal pain with abdominal fullness.He had a history of HCC rupture 10 mo ago and transarterial embolization was performed at that time.Abdominal computer tomograghy (CT)scan showed a huge peritoneal mass over the fight upper quadrant area.Surgical resection was arranged and subsequent microscopic examination confirmed a diagnosis of moderately-differentiated HCC.
