Amyloidosis associated with renal cell carcinoma of the AA type.

ABSTRACT

Amyloid fibrils were found at postmortem examination in a 70 year old woman with generalized amyloidosis associated with renal carcinoma (hypernephroma). Clinically, her amyloid disease presented as nephrotic syndrome. It was demonstrated by electrophoretic and amino acid sequence analysis studies that the amyloid fibrils contained AA protein identical to that found in amyloidosis associated with chronic inflammatory and infectious diseases as well as in the genetic form of familial Mediterranean fever.
