Plasmacytoma appearing as a tumor mass. One liver core was normal (Row 1 Left 40X). A triad with a proliferated bile ductule, otherwise normal (Row 1 Right 400X). The other core showed a mass of tumor mashed against normal liver (Row 2 Left 40X).

B cell lymphoma mimicking hepatitis with fibrosis. | |||
Apparent inflamed fibrous tract with lobular inflammatory collections in adjacent liver (Row 1 Left 40X). Apparent inflamed fibrous band between two relatively hepatocyte regions (Row 1 Right 40X). Apparent piecemeal necrosis with bile ductular proliferation (Row 2 Left 200X). Apparent portal inflammation with unaffected interlobular bile duct (Row 2 Right 200X). Apparent lobular inflammation with collections a bit too large for usual lobular inflammation. (Row 3 Left 200X). 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 (Row 3 Right 400X). | |||
