Malignant melanoma with metastasis into the capitate

Metastases to the hand and wrist are rare, with fewer than 200 cases reported in the literature. Phalanges are more commonly involved than metacarpal and wrist. The lung, breast and kidneys are the more common sites of primary lesions than metastasize in the hand. We present an exceptional case of melanoma that metastasized to the capitate. Melanoma can give bone metastases, but we are not aware of reports of this tumour metastatising to the carpal bones. In our knowledge, we have only found a report of metastases in the capitate, a clear-cell sarcoma of the right foot, a tumour close to melanoma with some cytogenetic differences. Hand metastases in a patient who is suffered melanoma should be ruled out if a lytic aggressive lesion appears on x-ray film or positive technetium bone scan is demonstrated.
