[Lipoblastoma. A rare, benign tumor in children].

Lipoblastoma is a rare, benign tumour of embryonal fat seen almost exclusively in infancy and early childhood. It occurs mostly in the extremities, but it is also seen in other parts of the body. The tumour may grow rapidly, and the fact that lipoblastomas show immature fat cells could lead to the wrong diagnosis of liposarcoma. Complete surgical excision appears to be the treatment of choice. A correct, preoperative diagnosis is possible in most cases. Two cases of lipoblastoma of the upper limb and one case in the scapular region are reported.
