Hepatocellular carcinoma, poorly differentiated (photo - upper right), developed on liver cirrhosis. This malignant epithelial tumor consists in tumor cells, discohesive, pleomorphic, anaplastic, giant. The tumor has a scant stroma and central necrosis because of the poor vascularization. In well differentiated forms, tumor cells resemble hepatocytes, form cords and nests, and may contain bile pigment in cytoplasm.
