Synovial fluid oxalate deposition complicating rheumatoid arthritis with amyloidosis and renal failure. Demonstration of intracellular oxalate crystals

H R Schumacher Jr et al. J Rheumatol. 1987 Apr.

Abstract

A patient with quiescent rheumatoid arthritis, amyloidosis and chronic renal failure developed an inflamed knee. Intracellular bipyramidal crystals characteristic of oxalate were found and are suggested as the cause of the acute arthritis. Since the patient had been treated with vitamin C, this precursor of oxalate is proposed as a possible factor in the crystal deposition.
