α​1 -anti-trypsin deficiency

α​1 -anti-trypsin deficiency, is an autosomal recessive disease marked by abnormally low levels of (serum) of this major protease inhibitor (Pi)
Deficiency of the enzyme leads to pulmonary emphysema (panacinar)
Liver is characterised by :
Presence of round to oval cytoplasmic globular inclusions in hepatocytes which on H and E stains acidophilic and indistinctly demarcated from surrounding cytoplasm.
They are PAS positive and diastase resistant
In most part, only distinctive feature is globules infrequently-fatty change, mallory bodies.
Neonatal hepatitis with cholestasis
Fatty change (steatosis)
Cirrhosis may develop which can transform into heptocellular carcinoma.
