Abstract

Reactive lymphoid hyperplasia (RLH) is a rare benign liver mass that is characterized by proliferation of non-neoplastic lymphocytes extranodally. To date, only 43 cases have been reported in the English literature and 2 cases in the Korean literature. We report a case of hepatic RLH in a 36-year-old woman who had been diagnosed two years previously with an intrahepatic tumor that measured 0.6 x 1.0 cm on abdominal ultrasonography. Her medical history was otherwise unremarkable. On follow-up ultrasonography, the hepatic mass had increased in size. We biopsied the liver mass and the histopathologic findings confirmed reactive lymphoid hyperplasia. Radiofrequency ablation (RFA) was performed instead of surgical resection. The patient is currently doing well with no sign of relapse 1 year and 8 months after the RFA.
