Abstract
A 71-year-old female was admitted to our hospital for evaluation of a hepatic lesion. She had a history of chronic type C viral hepataitis and chronic myeloid lymphoma which was treated by chemotherapy without relapse for 10 years. The ultrasonography finding showed a low echoic, solid, 23×25 mm mass in segment 5 of the liver. The tumor markers associated with liver malignancy were all negative. A slight elevation of liver function enzyme and soluble serum interleukin-2 receptor levels (753U/ml) were found. On computed tomography, magnetic resonance imaging, and angiography, the tumor had well-enhanced features similar to the hepatocellular carcinoma ; an anatomical resection of the liver was performed. The tumor specimen was a yellowish, clear-bordered, and uniformly solid mass. A diagnosis of reactive lymphoid hyperplasia of the liver was made based on immunohistochemistry. Thus,the patient was appropriately treated ; she has had no recurrence for 4 years.
