[Ankylosing gout. Apropos of 2 cases].
Development of ankylosis of joints involved with gouty arthritis is an exceedingly rare event of which only ten examples have been reported. Most patients had chronic, tophaceous gout that had not received adequate medical attention. The authors report two new cases including one in a patient with no documented history of acute gout. The first patient was a 72 year old noninsulin-dependent diabetic male who had been given a diagnosis of gouty polyarthritis with tophi seven years earlier. The second was a 42 year old male with no history of acute gout in whom hyperuricemia had been diagnosed at the age of 22 years upon evaluation for obesity. Both patients had ankylosis of the ankles and proximal interphalangeal joints of the hands. A marked decrease in range of motion of the wrists was found in the second patient. Roentgenograms showed complete ankylosis of the tarsus and partial ankylosis of the tibiotarsal joints in both patients, as well as ankylosis of the carpus in the second patient. The pathophysiology of ankylosis during gouty arthritis is poorly understood. A pannus containing abundant urate crystals is found upon pathological examination. Antihyperuricemic agents can reverse urate deposition but have no effect on ankylosis.
