[Children's tumors of the hand]

Soft-tissue and osseous tumors of the hand in children differ considerably from those of adults, not only in frequency but also in terms of anatomic distribution, histologic type and prognosis. Malignant tumors are rare in children, the most common being rhabdomyosarcoma for soft-tissue tumors, and osteosarcoma and Ewing sarcoma for osseous tumors. Hemangioma is the most common soft-tissue tumor in infancy and childhood. Other vascular abnormalities are capillary malformation, venous malformation. Many other benign soft-tissue and cutaneous tumors can be seen (ganglion cyst, naevus, fibroma...). The surgeon must know the signs, evolution and the treatment of these tumors.
