Wilson’s disease with cirrhosis in a 22 year old woman. A. Nodules show steatosis without definite triads. B. Trichrome shows minute fibrous bound nodules in this case. C. Reticulin shows extensive regeneration (2-3 nuclei thick cords with lack of direction) with nodule formation. D. Bridge with extensive proliferated bile ductules and acute and chronic inflammatory cells. E. Ballooning degeneration with Mallory bodies. | |||
