Three cases of liver abscesses complicated with colon cancer without liver metastasis: importance of screening for digestive disease.

We treated 3 patients complicated with colon cancer without liver metastasis, who were admitted to our hospital because of a high fever and diagnosed with liver abscesses. In a general screening after performing percutaneous transhepatic abscess drainage, colon cancer was detected in each, though hepatobiliary diseases were not found. Hepatobiliary diseases were the most common etiology of hepatic abscesses in our hospital in the past 41 cases from 1990 to 2005, 3 of which were due to colon cancer.
