Figure 2. Microscopic findings for patient 2. Left. A conventional hematoxylin–eosin stain shows only rare islands of surviving regenerative lobular cellularity (arrow). (Original magnification, x5.) Middle. Reticulin silver staining demonstrates dense condensation of fibers surrounding persisting ducts without any intervening lobules, except in the regenerative nodule (arrow). (Original magnification, x 5.) Right. Immunohistochemical stain for cytokeratin cocktail AE1/AE3 highlights the dense aggregates of ducts (arrows) uninterrupted by lobular elements. (Original magnification, x5.)
