[Present status of Poncet's tuberculous rheumatism. A new case].

A case of noninfectious polyarthritis of over one year's duration with calcaneal enthesopathy in a patient with visceral tuberculosis is reported. This pattern, termed Poncet's disease, shares pathophysiologic mechanisms with Freund's complete adjuvant-induced arthritis. Future studies should include polymerase chain reaction studies to look for the tubercle bacillus in joint fluid or synovial biopsy specimens.
