Figure 1

Schematic illustration of the histologic spectrum of benign hepatocellular proliferations. Polyclonal FNH is at one end of the spectrum and nontelangiectatic HCA is at the other; inflammatory HCA (I-HCA), formerly classified as telangiectatic FNH (T-FNH), has overlapping features and is shown in the middle. Gray areas indicate fibrosis; green and red dots represent bile ductules and arterioles, respectively.
