Generalized amyloidosis in cystic fibrosis.

A boy suffering from cystic fibrosis (CF) complicated by generalized amyloidosis is reported. His condition was fairly good during the first 10 years of life, but after this time he had repeated pulmonary infections caused by Staphylococcus aureus. From the age of 14, he developed increasing hepato- and splenomegaly and a liver biopsy revealed massive amyloidosis. At the age of 16 he died of respiratory and cardiac failure. Post-mortem examination revealed wide-spread amyloidosis in addition to pulmonary and pancreatic findings characteristic of CF.
