[Two adult cases of malignant hepatic mixed tumor]

Two adult males, aged 20 and 47 years, suffered from malignant hepatic mixed tumor. The common initial symptom was low grade fever and a large palpable tumor in the right quadrant of the abdomen. Macroscopically, these tumors were huge and elastic firm in consistency. Microscopic findings confirmed that the tumor cells possessed totipotential cell characteristics. Therefore, it might be conceivable that these two cases were malignant hepatic mixed tumor originating from the hepatic premordial cell.
