[Metastatic tumors of the hand in three cases].

Metastatic malignancies of the hand are rare and they usually develop from lung, breast, and kidney tumors. Metastases to the bones of the hand can cause pain, swelling, soft tissue ulceration, and osteolytic destruction. We presented three patients with metastatic tumors of the hand, whose ages were 58 (male), 42 (female), and 40 (male) years. Metastases developed in the thumb and the big toe, metacarpal bone, and the nail bed following treatment for primary tumors of the bladder, colon, and chondrosarcoma of the proximal femur, respectively. One patient underwent amputation of the thumb and the big toe followed by systemic chemotherapy, one patient with metacarpal involvement was treated with Ray amputation, and the latter underwent a biopsy. Histopathological diagnoses were consistent with primary tumors.
