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.
