Primary biliary cirrhosis. Two inflamed triads accompany acini with mild steatosis (Row 1 Left 20X). A triad bears a poorly formed granuloma [yellow arrowhead]. A bile duct is also seen [red arrowhead] (Row 1 Right 200X). A triad lacks a bile duct (Row 2 Left 200X). Trichrome of the same triad shows portal fibrosis (Row 2 Right 200X).
