We experienced a case of focal nodular hyperplasia (FNH) of the liver in a 50-year-old man. Fifty-seven cases of focal nodular hyperplasia reported in Japan in the light of the literature revealed that it was difficult to diagnose preoperatively and was a disease demanding definite differentiation from hepatocellular carcinoma (HCC).In this case, abdominal sonography, abdominal computed tomography and abdominal angiography failed to differentiate from HCC.It is generally said that histopathological diagnosis is important in diagnosing FNH, and we were able to diagnose it by histopathological findings of the resected specimen postoperatively. The first choice of the treatment of FNH, though it has been considered a benign disease, is thought to remove surgically, because it can be occasionally accompanied with malignancy or rupture into the abdominal cavity.
