Macroamylasemia

Overview
Macroamylasemia is a benign acquired condition, characterized by a serum amylase unusually large in molecular size that has been found to occur in apparently healthy humans as well as in a variety of diseases including liver disease, diabetes, cancer, malabsorption and autoimmune disorders. Most commonly macroamylasemia results from the formation of immune complexes between amylase and immunoglobulins.
