SZ phenotype alpha-1-antitrypsin deficiency with paucity of the interlobular bile ducts.
A child is reported whose alpha-1-antitrypsin phenotype is SZ and who has chronic cholestatic liver disease that began in the neonatal period. Liver biopsy demonstrated paucity of the interlobular bile ducts, marked hepatocellular deposition in periportal areas of PAS-positive, diastase-resistant granules, and bridging portal fibrosis. The association of paucity of the interlobular bile ducts with SZ phenotype alpha-1-antitrypsin deficiency has not been reported previously.
