FOCAL NODULAR HYPERPLASIA OF THE LIVER: A CLINICOPATHOLOGICAL ANALYSIS / 解放军医学杂志

ABSTRACT

cases of focal nodular heperplasia of the liver were studied with HE staining and immunohistochemistry. The patient population was composed of 12 males and 5 females, aged 13 to 71 years. The main symptom was abdomimal pain or discomfort. 9 patients were misdiagnosed as hepatic cell carcinoma (HCC) before operation. Histologically, 14 cases were of classical form, and 2 cases were of telangiectatic form, and 1 case mixed form. The classical form of FNH was defined by the presence of 4 characteristic histologic features nodular central stellate scar, abnormal nodular architecture, malformed vessels, and cholangiolar proliferation. The causes of focal nodular hyperplasia of the liver were briefly discussed.
