There was no lymphadenopathy or other abnormal signs. Ultrasound-guided needle aspiration biopsy confirmed adenocarcinoma. The surgery showed that the tumor was confined to the right lobe of the liver and a segmental resection of the liver was performed. The patient survived well after 1 1⁄2 years.
