Lipoblastoma on the posterior side of the neck

Lipoblastoma is a rare benign pediatric tumor derived from embryonic fat, and only two cases of lipoblastoma located on the posterior side of the neck have been reported in the literature. Here, we present the third case of posterior neck lipoblastoma in a 13-month-old healthy girl, who presented with a firm, posterior cervical mass. The tumor was completely resected following ultrasonography, computerized tomography, and magnetic resonance imaging evaluations. Histological examination of the resected tissue showed the typical characteristics of lipoblastoma. The child's postoperative progress was uneventful and no recurrence was observed 27 months after the operation. The clinical manifestations, radiologic and histopathologic findings, and treatment of this lesion are discussed.
