Systemic amyloidosis and hypogammaglobulinemia.

Small deposits of amyloid were found at autopsy in the kidneys, liver, spleen, and blood vessels of the intestines of a patient known to have primary acquired hypogammaglobulinemia. Previously described cases of hypogammaglobulinemia-associated amyloid are reviewed and possible pathogenetic mechanisms are discussed. The pathogenesis of amyloidosis in this patient is not known.
