Poncet's disease (tubercular rheumatism) with primary involvement of the foot - A case report.

We present a rare case with primary tubercular involvement of the foot, accomapanied by a reactionary (aseptic) effusion in the knee. The diagnosis was delayed due to unusual presentation and also because of failure to elicit a detailed history. Incision and drainage of the foot abscess and antitubercular drug therapy resulted in satisfactory control of tubercular infection. Polyarticular presentation may not always signify active tubercular focus in every joint; it may reflect reactive synovitis known as Poncet's disease, which resolves with multidrug antitubercular therapy.A multidispilinary approach should be adopted and chest physicians, rheumatologists and orthopaedic surgeons should work in close association to correctly diagnose and treatthis condition.
