A resected case of hepatic lymphoplasmacytic lymphoma in a patient with chronic hepatitis B virus infection

A 60-year-old woman followed up for arrhythmia, hypertension, and chronic hepatitis B was found to have a mass in the left liver on abdominal ultrasonography. Further examinations showed a tumor 40 x 30mm in diameter at segment III of the liver, and hepatocellular carcinoma was suspected. The lateral segmentectomy of the liver was done. Pathological findings for the tumor showed lymphoplasmacytic lymphoma. No lesions other than those in the liver were seen, so she was diagnosed as having primary hepatic malignant lymphoma, which is comparatively rare. This is the 19th resected case of primary hepatic malignant lymphoma reported in the Japanese literature, and the second resected case of hepatic lymphoplasmacytic lymphoma. If the tumor is localized in the liver, it would appear most effective to conduct both surgical resection and chemotherapy.
