Giant lipoblastoma of the thigh: a rare soft tissue tumor in an infant.

Lipoblastoma is a rare lipomatous tumor encountered almost exclusively in infants and young children. It arises from embryonic white fat. The common site of involvement is the extremities. In spite of their potential for local invasion, they are benign tumors. We report a case of a lipoblastoma in an infant and review the literature pertaining to clinical management of these tumors.
