Abstract

We report a rare case of a patient with multiple myeloma who developed hyperamylasemia not associated to hyperamylasuria and without symptoms of pancreatic or salivary disease. This condition suggested the occurrence of macroamylasemia, consisting of macromolecules of amylase bound with immunoglobulins, which are not filtered by the kidneys. Hyperamylasemia was not present at the diagnosis of myeloma and appeared at the relapse of the disease, simultaneously with the appearance of an additional γ-chain oligoclonal component, suggesting a possible role of these chains in producing macroamylasemia. To our knowledge, this is the first report of macroamylasemia in a patient with multiple myeloma.
