Axillary lipoblastoma--tumor recurrence in the right atrium.

This case report describes, for the first time, vascular invasion and recurrence of a lipoblastoma 6 months after the macroscopically complete excision of the initial cervico-axillary tumour. The importance of cytogenetics in the diagnosis of lipoblastoma is emphasized, as is the need to be wary of the diagnosis of lipoma in infancy.
