A 39-year-old woman presented clinical features of adult onset Still's
disease. Seven years after the onset, she developed renal insufficien
cy and biopsy studies revealed amyloid deposits involving amyloid A pr
otein, P component, lambda chain and kappa chain in the kidney and rec
tum. She died in 1992, primarily due to cardiac failure associated wit
h amyloidosis, indicating that amyloidosis should be considered one of
the fatal complications in adult onset Still's disease with a long hi
story.
