Tophaceous gout of the foot: an unusual presentation of severe chronic gout in an undiagnosed patient.

Tophaceous deposits are frequently noted within articular cartilage, synovium, tendons, tendon sheaths, pinnae and the soft tissue on the extensor surface of the forearms, feet, and bursae in patients with a history of chronic gout. The authors describe an unusual case of severe chronic tophaceous gout without prior diagnostic history or presence of acute attacks. They describe the procedure for the excision of these masses as well as the radiographic and pathological findings.
