| Metavir activity index 2 (Piecemeal necrosis 1, Lobular necrosis 2), Metavir fibrosis stage 4.  Hepatitis C genotype 1a. Inflamed bands separate hepatocyte regions distorted by steatosis (UL). Bordering tract and acini (UR) lymphocytes, macrophages, eosinophils, and rare neutrophils (black arrowhead) invest both proliferated bile ducts (yellow arrowheads) and hepatocytes, some showing ballooning degeneration (green arrowhead). Reticulin shows hepatocyte cords often two nuclei thick bounded by directionless sinusoids, consistent with a regenerative nodule (LL). Trichrome shows extensive bridging with a potential flattened nodule; although a debate about the presence or absence of definite fibrosis would have existed, with the Metavir scoring system, this is considered fibrosis stage 4 (LR).
