MANZONE, Patricio et al. Lipoblastoma de extremidades y tronco: recurrencia local y complicaciones después de la resección marginal. Estudio multicéntrico. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2022, vol.87, n.3, pp.349-359. ISSN 1852-7434. http://dx.doi.org/https://doi.org/10.15417/issn.1852-7434.2022.87.3.1358.
Objectives: Lipoblastoma is a rare benign neoplasm that resembles white fat and can occur as a localized (lipoblastoma) or diffuse (lipoblastomatosis) tumor. Due to its rarity, the literature is mostly limited to case reports. The purpose of this study was to determine the local recurrence rate and complications after marginal resection of lipoblastomas located in the extremities or the back. Materials and Methods: We performed a multicenter retrospective review of the records of pediatric patients who had undergone surgical excision of lipoblastomas at 4 tertiary care institutions from 2008 to 2018. We recorded the demographic data, diagnostic method, the volume of the lesion, type of biopsy, complications, recurrence, and the need for additional procedures. Results: Throughout the study, 17 patients met the inclusion criteria for evaluation. The average patient age was 3.9 years, and 65% were male. The most common locations included thighs (N 9), low back region (N 2), and buttocks (N 2). The mean preoperative mass volume was 305.5 cm3 (range: 10.2 cm3 - 1745.8 cm3). The mean duration of follow-up was 2.8 years (range: 8 months to 5.6 years). One patient experienced recurrence (5.9%). One patient had a retracted skin scarring in the gluteal area. Conclusion: Marginal surgical resection of lipoblastomas located in the back or extremities showed a low recurrence rate at 2.8 years of follow-up and minimal complications.
