Lipoblastoma of the neck: a rare cause of respiratory problems in children.

Lipoblastomatous tumours are rare, and they occur primarily in children younger than 3 years of age. They are benign and may be divided in lipoblastomas and lipoblastomatosis. A case with cervical lipoblastoma causing respiratory difficulty is reported, and a clinical characterisation of patients with lipoblastomatous tumours in the neck is presented.
