Primary "idiopathic" amyloidosis is usually related to immunoglobulin light chain (AL) associated with immunocytic dyscrasias, while secondary "reactive" amyloidosis (AA) is related to serum amyloid A protein (SAA) and typically occurs with chronic inflammation, malignancy, or familial Mediterranean fever. In the present study, amyloid fibril protein extracted from frozen and paraffin-embedded tissue from a patient (CAR) with primary systemic amyloidosis proved to be AA protein by immunohistochemical, immunochemical, and amino terminal sequence. Extracts from both frozen and formalin-fixed paraffin-embedded kidney and spleen yielded similar monomers and dimers of the AA protein. The additional high-molecular-weight bands and a distinct 12,000-dalton fragment in the amyloid protein extracted from the formalin-fixed paraffin-embedded lung suggest that different processing of proteins, ie, by polymerization and/or degradation, may occur in different organs.
