[[File:3 A1AT 1 680x512px.tif| Alpha 1 Antitrypsin deficiency with cirrhosis]] | Alpha 1 anti-trypsin deficiency in 29 year old woman. A. At low power, there is focal steatosis and mild inflammation of portal triads. B. Foci of steatosis show rare tufts of ballooning degeneration (arrow). C. A few triads had infiltrates of macrophages and lymphocytes, none with definite interface hepatitis; note the space between the hepatocytes and the inflammatory cells. D. PAS-D showed splotches of hepatocytes with PAS-D granules. The patient was already known to have A1AT deficiency. | ||

Alpha 1 Antitrypsin deficiency with cirrhosis. A. Dark inflamed bands bound hepatocyte nodules. B. Steatosis afflicts some hepatocyte areas, within inflamed band lie proliferated bile ductules. C. Reticulin shows regenerative (more than 2 nuclei per cord) nodules (black lines without definite directionality) amid bands. D. Trichrome shows scar. E. Hepatocytes show steatosis, foamy degeneration, and intranuclear inclusions. F. PAS-D shows A1AT cytoplasmic granules; in non-A1AT cirrhosis, these granules would neither be in so many hepatocytes nor, in general, as large. | |||

Alpha 1 anti-trypsin (A1AT) granules in cirrhosis, not due to A1AT deficiency; A1AT level was normal. A. Low power shows an inflamed foci, bands, and hepatocyte regions | Alpha 1 anti-trypsin (A1AT) granules in cirrhosis, not due to A1AT deficiency; A1AT level was normal. A. Low power shows an inflamed foci, bands, and hepatocyte regions. B. Trichrome confirms blue fibrosis about hepatocyte isles. C. Proliferated bile ductules (black arrows) border hepatocytes with glycogenated nuclei (green arrows), consistent with the history of diabetes. D. Reticulin shows two-cell thick regenerated cords (green arrows) and circles for rosettes (black arrows). E. PAS with diastase stain shows occasional small red granules (arrows) and red dust in cytoplasm of hepatocytes near edge of regenerative nodule. E. A1AT immunostain shows occasional small brown granules (arrows) in cytoplasm of hepatocytes near edge of regenerative nodule. | ||
