Successful surgical control for hepatocellular carcinoma disseminated to the peritoneum: a case report

Treatment for dissemination of hepatocellular carcinoma to the peritoneum has not yet been established. A case of a 62-year-old man who underwent curative resection for hepatocellular carcinoma 1 month after ultrasonically guided needle biopsy is presented. At 23 months after surgery, computed tomography revealed a mass in the abdominal cavity. At laparotomy 3 months later, a peritoneal tumor deposit directly invading the colon was resected in continuity with a portion of large intestine. The tumor was confirmed histopathologically to represent dissemination of hepatocellular carcinoma. No other lesions were detected 20 months after the second operation. Surgical treatment can locally control peritoneally disseminated hepatocellular carcinoma provided that lesions have limited extent.
