CT scan and histology of grade 1 PHNET. Post-contrast CT image of the arterial phase (a), the portal venous phase (b) and the delayed phase (c) shows marked enhancement in the PHNET relative to the liver parenchyma (right lobe at the arterial phase), and slight hyperattenuation relative to the surrounding liver parenchyma in the delayed phases. The integrity of the capsule is maintained. The mitosis rate shows up as hypo-density and no enhancement on the dynamic enhanced CT scan. HE staining of the tumor (d) shows tumor cells arranged as solid nests, consistent cell size and mitosis rate was 1/10 HPF. Magnification: D = 100X
