Abstract
Two cases of tophi were reported. One of them (38-year-old male patient) was diagnosed erroneously as a malignant tumor from synovial origin because of its roentogenological marked destractive bone changes of first MP joint of left foot, another (71-year-old male patient) was as a xanthomata of tendon sheath.
Both cases were diagnosed as gouty tophi immediately after skin incision. Those facts teaches us that gout should be kept in mind in diagnosing tumor of foot or hand.
