Alpha1-antitrypsin deficiency--an association with hepatic malignancy.
A 70-year-old man with homozygous alpha1-antitrypsin deficiency (AATD) (Pi-ZZ phenotype) at tutopsy was found to have a hepatocellular carcinoma and hepatic fibrosis, pulmonary emphysema, and cor pulmonale. Characteristic cytoplasmic inclusion bodies, with identical histochemical and ultrastructural features, were detected in both normal and malignant liver cells. It is suggested that AATD may precede malignancy, since this is the eleventh case report of this association.
