[Resected hepatocellular carcinoma with macroglobulinemia--a case report].

A 54-year-old man had been diagnosed as having macroglobulinemia 10 years earlier; Ultrasonography and liver scintigraphy showed a space-occupying lesion in the right lobe of the liver; CT scan showed abnormal density in the same region. IgG was more than 7,000 mg/dl. The tumor was isolated, and liver function was good. On laparotomy, biopsy of the tumor and one of the enlarged lymph nodes in the hepatoduodenal ligament was undertaken. The diagnosis the from frozen tumor section was hepatocellular carcinoma; malignancy was not found in the lymph node. Right lobectomy was done. The patient left the hospital two months later after an uneventful recovery.
