B cell lymphoma mimicking hepatitis with fibrosis. A. Apparent inflamed fibrous tract with lobular inflammatory collections in adjacent liver. B. Apparent inflamed fibrous band between two relatively hepatocyte regions. C. Apparent piecemeal necrosis with bile ductular proliferation. D. Apparent portal inflammation with unaffected interlobular bile duct. E. Apparent lobular inflammation with collections a bit too large for usual lobular inflammation.  F. Proof is at high power. All cells are similar to macrophages but are too closely crowded to be macrophages. The monomorphism (one type of cell) should inspire immunohistochemical stains, which showed the patient had a B cell lymphoma.
