  • Title: Surgical management of lipoblastoma.
    Author: McVay MR, Keller JE, Wagner CW, Jackson RJ, Smith SD.
    Journal: J Pediatr Surg; 2006 Jun; 41(6):1067-71. PubMed ID: 16769336.
    Abstract:
    BACKGROUND/PURPOSE: Lipoblastoma/lipoblastomatosis, a rare benign pediatric tumor composed of embryonic fat, most often presents as a rapidly growing mass in children younger than 3 years. This benign tumor locally recurs up to 25% of the time. This retrospective review was done to emphasize problems with diagnosis, management, and the approach to follow-up care. METHODS: Sixteen cases of pathologically proven lipoblastoma presenting to a single institution over a 16-year period (1988-2004) were reviewed retrospectively for clinical features and outcome. RESULTS: There were 11 males and 5 females ranging in age from 18 days to 12.75 years. Preoperative diagnoses were accurate in only 3 cases. Two lesions recurred locally over a period of 10 months and 5 years. One lesion presented with local infiltration. Six lesions were right-sided, 5 were left-sided, and 5 were midline. CONCLUSIONS: It is important to consider lipoblastoma in the diagnosis of a rapidly enlarging fatty mass in children. Complete resection is the only definitive treatment and should not be delayed when impingement on surrounding structures is imminent. There is a tendency for these lesions to recur despite presumed complete excision. Therefore, follow-up for a minimum of 5 years is recommended.
