A case of primary systemic amyloidosis

Area of Science:

• Cardiology
• Nephrology
• Pathology

Background:

• Primary systemic amyloidosis is a rare plasma cell disorder.
• Nephrotic syndrome and cardiac conduction abnormalities are potential manifestations.

Observation:

• A case of slowly progressive primary amyloidosis presenting with nephrotic syndrome and complete atrioventricular (A-V) block is detailed.
• The patient experienced prolonged poor appetite and nephrotic syndrome.
• Temporary cardiac pacing was ineffective, likely due to intrinsic myocardial damage.

Findings:

• Autopsy confirmed primary amyloidosis through light microscopy and immunofluorescence.
• Amyloid deposition was evident in cardiac tissues.

Implications:

• This case highlights the complex presentation of primary systemic amyloidosis.
• Early identification of cardiac amyloid infiltration could potentially enhance treatment strategies and patient prognosis.
