Isolated Metastatic Lesion of the Trapezium

Abstract not available. Introduction provided instead.

Hand metastases are rare. Their incidence among all metastatic lesions is only slightly more than 0.1%. The distal phalanx is the most commonly involved site of hand metastases. Pancarpal involvement is more common than isolated carpal metastases. A solitary carpal metastasis can pose a diagnostic dilemma, as it mimics acute arthritis, osteomyelitis, and avascular necrosis, and, up to 16% of the time, it may be the first indication of a primary cancer elsewhere. An isolated metastatic lesion of the trapezium is reported for the first time.
