ABSTRACT
In 1897, Poncet described polyarthritis in patients suffering from tuberculosis which was not caused by tuberculosis infection of the joints. Poncet's disease is characterized by a polyarthritis that occurs during the acute tuberculosis infection in which no mycobacterial involvement can be found or other known cause of polyarthritis detected. It is a different entity from tuberculous arthritis, which is usually monoarticular and is caused by direct tuberculous infection. It was little known for pathogenesis of Poncet's disease, but immunologic reaction was suggested. Poncet's disease is associated with an excellent prognosis with rapid resolution on commencing therapy and no sequelae. Therefore, recognition of Poncet's disease can be important. Poncet's disease remains a diagnosis of exclusion.Recently, we experienced one case of Poncet's disease which have characterized by the clinical manifestations, and report this case with a review of the literatures.
