A diabetic patient is undergoing dialysis. Aspiration done around the knee joint would show which of the following?

Chronic renal failure patients undergoing long term hemodialysis develop amyloidosis. Amyloidosis in such cases is associated with the deposition of a protein called A- b2 microglobulin. Such amyloid deposits are common in synovium, joints and tendon sheaths. So an aspirate obtained from knee joint would likely reveal A- b2 microglobulin.Ref: Pathologic Basis Of Disease, Robbins, 6th Edition, Page 253; 7th Edition, Page 260, 261.
