Lipoblastoma arising from the submandibular region.

A lipoblastoma is a rare, benign tumor arising from embryonic white fat. The tumors occur primarily in infancy and early childhood and commonly arise from the limbs and the trunk, but neck involvement is extremely rare. Our case arose in a 22-month-old male presenting with a rapidly enlarging soft mass in the right submandibular area. Lipoblastoma was diagnosed by histologic evaluation, the mass was completely removed, and there was no recurrence at 1-year follow-up.
